Using Mail() And Avoiding Spam Boxes !
Im using the mail() command to send an email to people who register on
my site, but many are ending up in people's spam boxes on hotmail.

This problem isn't true of all users - probably around 60%.

Im being as open as possible using a number of headers, but can anyone
suggest a way of getting through with less problems ?

$sender = "From: Name <email@domain.com>" . "";
$sender .= "Return-Path: email@domain.com" . "";
$sender .= "MIME-Version: 1.0" . "";
$sender .= "Content-Type: text/plain; charset=iso-8859-1" . "";
$sender .= "Content-Transfer-Encoding: 8bit" . "";
$sender .= "X-Mailer: PHP/" . phpversion();

Avoiding Php Mail() To Spam Boxes
I'm sending soliticited emails for a nonprofit and i'm finding when i use PHP's mail function, and the mail goes through my ISP's SMTP, a decent percentage of the mails go to people's spam boxes.

are there known headers or something i could add to my code to make them less spam box prone?

Mail() / Sendmail Sending Mail As Spam
Wondering if anybody knows why when sending mail through my local sendmail program using the PHP mail() function; emails either do not reach the destination, or register as spam? Prime example is: h0tm@il addresses never receive the email, gmail addresses consider the email to be spam, and my workplace receive the email about 1 hour after the program finishes.

Could it be a problem with my ISP? I am using Fedora Core 6, PHP 5 and Apache 2. Or test it yourself.. just fill out the form with some rubbish and it should send an email saying you've registered.. maybe you can figure out where I am going wrong by looking at the headers? http://aaronweb.no-ip.com:6969/?p=2

PHP Mail Flagged Aas SPAM
I am developing a web site using PHP that delivers several different email
formats. I am testing with another server where the messages are sent and
some of these messages (not all) will be flagged as SPAM. The headers are
identical for those that work and those that don't only the body of the
message is different. Can some give me some insite into this and what are my
options to insere that various mail servers do not flag them as spam? I am
using PHP Mail to create all of the messages.

I've been doing a lot of Google searches but for some reason I'm not finding
any solutions.

Thanks,

PHP Mail() And AOL Spam Filter
dodging AOL's spam filters when mail()ing
from PHP?

We are having trouble with this code:

$fromEmail = 'aValidAddress@thisHostAccount.com'

$headers = 'MIME-Version: 1.0' . "
";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "
";
$headers .= "From: This Foundation <$fromEmail>
";
$headers .= "Reply-To: This Foundation <$fromEmail>
";
$headers .= "Return-Path: $fromEmail
";
$headers .= "Message-ID: <".time()." TheSystem@".
$_SERVER['SERVER_NAME'].">
";
$headers .= "X-Mailer: PHP v".phpversion()."
";
mail($to, '$subject, $msg, $headers);

We had originally been sending bounces to a different Return-Path
address (see below) but simplified this after AOL flagged all the
emails as spam. Also the To field is being set like this
RealFirstName RealLastName <Addressand the message has a greeting
using the RealFirstName.

mail($to, '$subject, $msg, $headers, "-f bounce3@gnosports.com");

Php Mail Form And Spam
I have a feedback form on my site. People can fill the fields and
message is sent to me using 'mail' function, after the form gets
submitted (POST).

The fields are subject, from and text. 'subject' is optional, others
are mandatory. PHP script that handles the form input takes in account
predefined field names only.

The problem is that someone is sending me spam using that form. I
don't believe that they target me specificaly. It is more likely that
some automated robot is doing that. I tried to change field names, but
still getting the messages. I checked the message source, and they are
comming from the form.

My question is how they can guess the field names and determine which
mean what by automated process ? I guess they can parse html form to
get names, but how they can put values in proper fields ? Are they
using trial and error ? I should get messages with text in subject
field, too, then, but I don't.

Mail() Detected As SPAM
I use mail() a lot for sending emails to customers but many customers don't
receive my emails as they are considered SPAM emails. How to avoid this ?

I've to say that my ISP is sometimes in the spamcop blacklist, but in this
case I receive notifications from spamcop servers, but even when I don't
receive such notifications, some customers don't receive my emails.

Mail() Php Blocked As Spam
I created a simple php mail() function with attach. The problem is that I´m receiving the mails as spam, I already tried everything, maybe somebody could give me a help, my headers:

$remetente = "$nickuser"."@yachtbrasil.com.br";
$nome_resposta = "$nickuser";
$headers = "MIME-Version: 1.0".$eol;
$headers .= "From: $nome_resposta <$remetente>".$eol;
$headers .= "Reply-To: $nome_resposta <$remetente>".$eol;
$headers .= "Return-Path: $nome_resposta <$remetente>".$eol;
$headers .= "Content-type: multipart/mixed; boundary="$mime_boundary"".$eol;
$headers .= "Message-ID: <".$now." TheSystem@".$_SERVER['SERVER_NAME'].">".$eol;
$headers .= "X-Mailer: PHP v".phpversion().$eol;

Mail() Script Getting Filtered As Spam
Using PHP 4, I developed a form to be submitted and emailed. Our PHP
server is internal. Our company uses Yahoo's Mailsender.net for email.
The email never arrives to my Mailsender.net account. I am assuming it
is filtered as 'spam'. I do not know how if I need the email header
fields to have specific values to get by the Mailsender.net spam
filters. Anyone have experience with this?

I have tested my script and successfully sent emails to my Yahoo email
account (I use for personal stuff). At first the emails were sent to
my Bulk Mail folder (identified as spam for me to delete), but I made
a couple modifications in the header fields and now the emails arrive
in my Inbox folder.

Mail() Blocked By Spam Filter
I never had problem with this PHP page with mail() function with at
least 5 different servers, but email sent through the server of this
"T" company tends to get blocked by spam filters. I tested with my
different email accounts and these are the results.

* The mail is delivered to the "Inbox" of my AOL account.
* The mail is delivered to the "Bulk Mail" folder of my hotmail and msn
accounts.
* The mail is delivered to the "Spam" folder of another account of
mine.
* The mail is not delivered to any of my two university accounts.

One thing I noticed is that this "T" company hasn't setup the "From"
section, unlike the other servers that I worked with before, so the
mail is coming from "Nobody" <nobody@________>. I suggested the tech
person of the company update the "php.ini" file, but he doesn't admit
that's the issue. I tried manually adding the From with PHP coding
with "$headers," but it didn't make any change.

Mail Arrives In Spam Folder
I have been trying to figure this out and have used 2 classes already, but still am unable to get this working. I'm trying to send an email verification link out to each user that registers on the site, but Gmail has been putting it in the spam folder. Here's a copy of the message: Code:

Mail() Function Is Being Labeled As Spam!
I'm in a rather desperate situation and need some help. I've recently started a PHP-based website that seems to be taking off quite a bit. It has a user registration process in which users confirm their accounts via an email. Currently, 25% of these emails are not delivered (or received), primarily to the following account types:

*aol.com
*aim.com
*sbcglobal.com
*comcast.net

And occassionally Gmail and yahoo.

The site uses mail() to send them out, but the mail relay server is the same one used by all other clients my hosting company has (GoDaddy).

This means that when I send an email, it says the "From: " is the email address I choose, but the "Mailed-by:" says some nasty long name like "k2.smtp.secureserver.net"

Some email recipients report no problems at all. I thought one way to solve the problem would be to use some kind of SMTP-authenticated class library such as PHPMailer. I used that, and it actually resulted in even more emails being labeled as spam. I'm really confused.

Anyone know how to get around this issue? I've email GoDaddy plenty of times and they don't even bother responding.

Mail() Question, Helping Conform To Spam Filters
I am writing an application which shoots out confirmation emails to
friends and contacts --- and looking at the Beta of Outlook 12 for
Windows Vista, it looks like it catches this mail as Spam, where-as
Outlook 2003 and others cleared them just fine. I am also having
trouble with Yahoo as well. Yahoo and Outlook could just be too
sensitive, but I am worried some of my mail may not be getting thru.

This leads me to a question, what are the -basic- things I need in a
mail() header - so I can feel confident they are all present and
accounted for, and getting my most systems?

There is an odd checkbox/feature in Outlook 12 - "When sending e-mail,
Postmark the message to help e-mail clients distinguish regular e-mail
from junk e-mail".

Is this a technique that can be used in PHP, and has anyone had any
success with it?

Preventing Spam Drones From Abusing Our Mail Scripts
How do I prevent spam bots from exploiting php scripts that send mail?

Company's Form Mail Script Jams To Spam Filter
I have a problem, because we have a simple script that sends mail from (our
client) company's website to that company's boss. But just some days ago
post stopped coming, suppose because that email provided he's using
implemented more strong spam filter after some spamming attacks. Now that
program in my opinion seems to think that our form mail is spammer! I
suppose it must be about header information. How can I get our form working
again?

We only have used simple mail command with to, subject and message - no
additional headers. But now?

*************************
Here is docs from php site, so you dont have to find them :-)

Example 2. Sending mail with extra headers.
<?php
mail("nobody@example.com", "the subject", $message,
"From: webmaster@{$_SERVER['SERVER_NAME']}
" .
"Reply-To: webmaster@{$_SERVER['SERVER_NAME']}
" .
"X-Mailer: PHP/" . phpversion());
?>

The additional_parameters parameter can be used to pass an additional
parameter to the program configured to use when sending mail using the
sendmail_path configuration setting. For example, this can be used to set
the envelope sender address when using sendmail with the -f sendmail option.
You may need to add the user that your web server runs as to your sendmail
configuration to prevent a 'X-Warning' header from being added to the
message when you set the envelope sender using this method.

Example 3. Sending mail with extra headers and setting an additional
command line parameter.
<?php
mail("nobody@example.com", "the subject", $message,
"From: webmaster@{$_SERVER['SERVER_NAME']}",
"-fwebmaster@{$_SERVER['SERVER_NAME']}");
?>

Sendmail Page: How Do I Hide My E-mail Address From Spam Bots?
how to make a sendmail script without having to place my e-mail out on the web page where a spam bot can get to it? I need to hide my e-mail address on the hosting away from the spam bots.

Avoiding Load Time?
I have a script that takes quite a long time to load since the PHP is processing quite a lot of info. Is there any way I can initiate the script, then have it move on to another page right away so I don't have to wait for the PHP to finish processing? (having ignore_user_abort(); on so it will continue to process in the "background" - if my thinking is correct...)

Avoiding Duplicate Results??
Does anyone know if this is possible:

I'm running a query against a db and am pulling name and ticket # (for a helpdesk)...  What I'd like to do is take the results from the "Name" field, but only show EACH NAME ONCE in a table.  For example, I might get 200 results back, but only want to show the name of the person once, with how many tickets they have assigned to them.

So it would look like this:

___Name___|___Number of tickets___
___Bob____|__________3__________
___John____|_________23__________
___Mark____|_________4___________

...etc, etc...  does anyone know how to go about starting this?  I'm assuming an array of sorts. 

Writing A Review App But Avoiding Spamming
I want to write a revie module for some listings I have but I can imagine people posting 100s of times to say how great they are and 100s of times to slate their competitors.

I figure only allowing one review per listing from a particular IP address is a good start any other suggestions?

Avoiding Duplicate Array Elements
Im having a problem with this code. Im
trying to remove duplicate elements from an array created via $_GET.
I want users to be able to click on a link which sends an email
address to an array. I just want to remove duplicate email addresses
from the array. Ive tried array_unique() on my test server but it
doesnt work. So i tried to remove duplicates myself before storing
them into the array. The script works great without the checking,

session_start();

$email = $HTTP_GET_VARS['email'];
if (isset($_SESSION['Array']))
{

$Array = $_SESSION['Array'];
$numElements = count($Array);
for($counter=0; $counter < $numElements; $counter++)
{
/* Problem is here */if ($Array[$counter] == $email)
{
exit();
}

else
{
array_push($_SESSION['Array'],$email);
$EmailArray = $_SESSION['Array'];
$_SESSION['Array'] = $EmailArray;
}
}
}

else
{
$EmailArray = array();
array_push($EmailArray,$email);
$_SESSION['Array'] = $EmailArray;
}

Avoiding Endless Conditional Statements
Here is my problem. I want to make a webapp that will basically take
the work out of finding what tool works for what situation. There are
5 factors that go into tool selection. 1)Material Group, 2)Insert
Radius, 3)Insert Type and Size, and 2 others that I can't remember
off-hand. There are probably about 1000 different scenarios that I
have to code for..(there are several blank table cells and it's not
setup as you might imagine, there is a lot of overlapping), and I
desperately want to avoid making a gigantic conditional statement. I'm
afraid that I really have to provide a picture of what I'm doing here,
so I will do that. Here is the link.
You only see 3 of the 5
factors on this page, and the other 2 have to do with whether this
table or one of many other tables (not pictured) will be used.

So, now that I've confused everyone. That's my table. What's a good
way to go about programming that sucker in so that people don't have to
do all the "work" involved to figure out what tools they need. They
should just be able to choose selections from 5 dropdown boxes and get
one tool back. A tool is something like "10.655.600".

PHP File Writing And Avoiding A Race Condition
So, PHP has this issue where you cannot lock a file until you open it, which leaves the door open for a race condition when writing files. I wrote the following code a while back and think it should work (and in fact use it and it works), I just thought I'd post it here for an audit and in case it might be useful for someone to use or I missed something!

/**
* Write a file to the server.
*
* First open a temp file for writing and acquire a lock.
* Proceed to write, unlock and copy the file from a temp file. If the
* file size is the same, the write worked, clean up and go home. if
* not, clean up and hope it works the next time.
*/
function cms_writeFile($filename, $tempfile, $data) {
$ft = fopen($tempfile, 'w');
if(flock($ft, LOCK_EX)) {
fwrite($ft, $data);
flock($ft, LOCK_UN);
fclose($ft);
if(copy($tempfile, $filename) && filesize($tempfile) == filesize($filename)) {
unlink($tempfile);
return true;
} else { // The whole process failed.
unlink($tempfile);
unlink($filename);
return false;
}
} else return false;
}

I pass it a random tempfile name, so at that point I think we avoid any race condition issues, but to be paranoid I check the file size after the copy. If the files are of a different size, I drop them both and hope this works the next time.

An example to use the function:

if(cms_writeFile('test.php', 'randomg-temp.php', 'some data')) {
echo 'written'
} else {
echo 'notwritten'
}

Seems right, and it works, am I missing anything?

Is Spam Getting Through
I have been receiving these e-mails but have security on the PHP
form, however I would like to know if these messages are getting
through to their intended places or does my security work. I am
particulary worried about the reference to BCC because that is not part
of the form.
MORE IMPORTANTLY: How can I read this e-mail and know either I have
stopped it or I haven't?

I would be thankful to any help

Odd Spam (slightly OT)
I have a php contact form on a page that I manage which is receiving
replies such as the following:

Comments: Hello dear webmaster. I found your site via google and i like
it very much. cia!!
Subject: General query
Name: Senrde
Email: Snosjk@hotmail.com
Sent from IP: 203.162.27.93

Comments: i thinks you made i great web resource

Subject: General query
Name: Dansiz
Email: sdegnu@hotmail.com
Sent from IP: 204.174.87.210

Comments: Hi. dear webmaster i like your site.
Subject: General query
Name: Densdly
Email: dedlsa@hotmail.com
Sent from IP: 203.162.27.90

The comments line seems to come from a bank of about 5-10 but the names
and email addresses seem to be randomly generated. But what's bugging
me is why someone is doing this? It's not vast numbers, about 8
yesterday. IP addresses vary, Vietnam, and Japan appear quite a bit but
I've also had one from the UK. There doesn't seem to be any payload,

Phpmailer And Spam
I'm using phpmailer class (http://phpmailer.sourceforge.net) to send
mails from my site, but i can't figure out why those mails are seen as
spam by yahoo and hotmail. Gmail seems to look them better and allows
them to stay in "inbox" folder.
Are there any thing I can do about that?

Captcha And Spam
I have a simple guestbook up, and have implemented a captcha area to try to lessen the amount of spam. I have also banned a list of about 400 IP addresses known to be open proxies, or spam originators. But *still* i get a few a day and it's getting tiresome.

Is there something i am not doing right from a server side if they are somehow able to get around the captcha thing? (it works correctly, have tested) I thought that really could tell computers and humans apart.

Spam Flagging
I have a website where users submit anonymous messages, which are automatically posted publically on a rolling list. I am trying to implement a community flagging/voting system so users can eliminate spam messages themselves. I would like a flag icon to pop up next to each submission, and for entries to be deleted from the database (or at least not displayed) after 3 user flags. Code:

Contact Form Spam - To Me Alone
I have a contact form on my site (been there for a few years) and just
lately someone has begun using it to send Spam to me - and only to me
(one to three times a day). I can tell because I track the usage of
those contact form scripts (that I wrote) closely. The person is not
even trying to inject anything into the headers, they are just sending
me URLs to their porn sites.

Is there any way to block this kind of usage? I've tried the usual
tricks (hidden form field - checking referrer), but they always (almost)
check out okay. The originating IP address changes every time, of
course - and the porn sites are usually already gone.

I'm already cleaning all my form variables (checking for LF and CR and
content_type and cc:), so that is not my problem. It's just the few
annoying emails I get.

[ ..... Is this actually a productive way for spammers to distribute
their crap ... one email per form?]

Keeping Spam Bots Out
Is there a PHP-way of entering an email address on a .php webpage (as in "If you need info, email us at URL") with this address as a mailto link yet is NOT readable by spam bots who visit the site? I've searched the forum and found lots of "spam' references, but none of them talked about how to obfuscate a regular mailto link.

Form Spam Prevention
I'm looking to set up a jobsboard on my website and have bought a script to handle the applications through a form. The script prevent the form being hijacked for bulk email but there's nothing to stop robots making repetitive spam postings unless I insert a captcha code which will obviously slow down users.

So the question is if i don't use a captcha code do you think there's much of a risk of having spam through these forms? I've noticed kijiji.com requires captchas on its advert reply form but totaljobs.com (a large jobsboard in the UK) doesn't use captchas - how do they prevent spam problems or do you think they accept a small amount of spam will happen and think its not worth inconviniencing users with captchas to prevent the spam?

JS Redirect Spam Blocking
Basically I run a blog site with templates that I like users to have full control of. Unfortunately there are those spammers that like to throw in a javascript redirect. The normal ways of checking are currently hardcoded in my DB but I did not have a way of checking when they put them into variables or included them as a .js file inside the script.

This script will build the variables and or find the the url that the script is linked to and check the contents, if that script re-directs it will check the contents of the next until no more scripts are there to check or it finds a re-direct keyword. This worked on my 5 tests outlined below, but yea. Code:

PHP Registration Emails Marked As Spam
I have a "friendster" type website that sends out an email notification after a visitor has signed up. Visitors have to click on the link in the email notification in order to verify the membership. Unfortunately, most of my visitors aren't getting those emails because they end up in their spam folder.

Competitors, such as Myspace, Friendster, Hi5, etc. are able to avoid the spam problem. What are they doing differently? My site is built in PHP. So are my competitors' websites. Can someone offer a solution?

Prevent Email From Being Classified As Spam
I am trying to understand what I need to do to prevent emails from
going into the junk folder. Leaving consent aside, here is what I've
found so far:

1. Return-Path and From should have valid email addresses;

2. Better have the recipient NAME together with his email address;

3. Plain text email is reportedly safer than HTML;

4. Use HELO protocol (still need to figure out what this is and if I
can use it with PHP's mail() function);

5. Remove the X-Mailer header (saw this recommendation in some posting,
not sure if true).

Would very much appreciate additions to this list. E.g. should I have
the MESSAGE-ID header and why?

No Mercy Anti-Spam Script
I've been working on an anti-spam email PHP script for one of the sites I'm developing. The script is designed to be a generic script which can be reused across multiple sites.

It works in multiple stages:
Sending form must send a returning url variable. If it does not, the script shows a general error. This is intended to prevent cross site scripting hacksHTTP_REFERER must be in an allowed array which I maintain. If HTTP_REFERER is null or is not contained in this array, an error is returned.Email address must be syntactically valid, otherwise an error is returned.REMOTE_ADDR is checked against a blacklist of known spammer IPs. If the REMOTE_ADDR is in the list, an error is returnedAll fields are checked for spam keywords against a list of common spam words. If any spam words are found, the IP is added to the blacklist and an error is returned.Finally, the recipient address is hard coded so emails come to me and me only.

Now...I'm after feedback on how this works. Am I going overboard ? Is there any additional security measures that I should be taking ? I have considered adding a hash key system to the script, would this be overkill ?
