Getting an error periodically when someone posts to the board and it doesn't get sent to the email list.

The error in fudform can be seen here: http://seanwilson.org/errorlog.png

The error from my webhost says this:

ALERT - mail() - double newline in headers, possible injection, mail dropped (attacker '130.108.145.81', file '/hsphere/local/home/ludwiggroup/seanwilson.org/forum/theme/sean3/post.php' , line 2721)

The web host then writes, "Probably error appears when message is created incorrectly and header of new email is corrupted. This issue is related to the application and the way it creates email. Please re-check it from your side when error appears next time on your board."

Any help on this?

The message that failed to send was this one: http://seanwilson.org/forum/index.php?t=msg&th=3898&goto=6823&S =21881c28718eae48ec5cece03ef392f4#msg_6823

This looks like a bug in mlist_post.inc. Can you please add some debugging code to the bottom of the script to capture the message?

PS: I assume you are running 3.0.2.

... yes, 3.0.2.

I'm not sure I know what debugging code is. I have a php book (5.3) on my shelf. And I do fool around with code some. Can you give me some idea of where to start with this? I'll give it a go as soon as I can.

Yours, always very appreciative.

Add something like this just before the send_email() call:

$fh = fopen($GLOBALS['ERROR_PATH'] .'debug.msg', 'w');
fwrite($fh, "$header\n\n$final_body");
fclose($fh);

The code is obviously untested, but should get you started.
