PHP List,
I run a few various social groups, and with each one I keep in contact
with members by emailing them short newsletters.
All my user information is stored in a MySQL database. I use PHP to get
the relevant contact information, and use the mail() command to send out
the emails one by one, so that each email is a little personalized.
I've used this system for many years now with no problems up until now.
What has changed, though, is that in recent years, anti-spam measures
have become so aggressive that more and more people who sign up to my
groups complain that they never receive the emails.
A lot of the times, after they alert me to the issue, I can educate them
a little about the anti-spam measures they most likely have on their
system, and walk them through how to make it so that my newsletters go
through.
However, that is clearly not enough.
To shorten a story that has already gone on a little long, it's come to
my attention that part of the reason that my emails may not be getting
through are because the headers are not sufficiently legitimate looking
enough to bypass some server side anti-spam measures. Things like
"Return-Path" are being set so that they look like they come from an
email address that begins with the username "nobody".
If possible, can anyone help me with creating the PHP code that will
make an email as legitimate as it can be? I know I can't totally prevent
my email from being marked as spam (after all, if it were possible, all
the spammers would do it). But as much as I can prevent anti-spam
measures getting a false positive when testing my email, the better.
Here is the PHP code I currently use (trimmed for clarity):
while ( $member = mysql_fetch_row($mysqlResult) )
{
$subscriber = $member[0];
$email = $member[1];
$subject = "Report for " . date('l jS F Y');
$mailContent = "This is an email to " . $subscriber . " at " . $email . ".";
$fromAddress = "info@xxxxxxxxxx"
mail($email, $subject, $mailContent, $fromAddress);
}
And here is what the headers for an email from that code looks like:
-Account-Key: account5
X-UIDL: UID497-1152485402
X-Mozilla-Status: 0001
X-Mozilla-Status2: 00000000
Return-path: <nobody@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
Envelope-to: info@xxxxxxxxxx

Which parts are key to change, and how?
Thank you for any and all advice.
