I have been using FUDforum in conjunction with my (Arrow) mailing lists for three years and in general things have always gone well.
FUDforum has sent anything posted directly on it to the list, whilst not sending back anything it received from the list.
However, in the last week, for no reason that I can think of as I haven't changed anything, it is sending every message back to the list, even those sent from it.
I know the piece of code in maillist.php which makes sure something doesn't get posted from the list to the forum twice (i.e. the check for the X-Mailer header) but I can't find the corresponding code to stop posts from the list being sent back to it. How is this checked?
If somebody could point me in the right direction to see where to look, I'd be grateful.
BTW, I'm using the latest version (2.8.1)

Thanks, but I know that and that side of things is working OK. It isn't the forum that's getting the duplicates it's the mailing list. In other words, it's exporting, not importing that's the problem.
Most of my traffic originates as traffic to the mailing list. This sends a copy to the forum, which posts it. If a message originates on the forum, it sends a copy to the list, the list sends it back and it is recognised as a duplicate. So far, so good.
But until a week or so ago, a message sent from the list to the forum was posted to the forum but NOT sent back to the list. In other words, the software knew not to return posts originating from the lists.
Suddenly, it has started doing so (after three years of working perfectly) and I don't have a clue why.
The messages are collected from the forum incoming mailbox by getlists.php as a cron job.
If it helps, I can post a copy of both an original message and the copy sent back by the forum.

It will help if you can post (or mail me) their headers.
|
Firstly, I have to say that I've found a kludge round the problem which I'll explain in a separate reply.
However, here are the headers you asked for:
Firstly, of the main as received by the mailing list after it has been processed by my mail server (Hamster), hence all the X headers.

I have found a way round this problem.
I have got the mailing list to add a small footer to every message. I have added a routine to mlist_post.inc to check for this footer in the last 160 characters of an outgoing message. If it finds it, it sends the message to a trash account I've set up (once I'm certain it works perfectly it will simply not send anywhere). If it doesn't find the footer, it processes the mail as before.
I'm not a programmer, and I'm sure that my coding is bad, but for what it's worth, here it is:
mlist_post.inc (as amended)
function mail_list_post($list_email, $from, $subject, $body, $msg_id, $reply_to=null, $attch=null, $attach_mime=null, $additional_headers=null)
/** Original code **/
$multi_part = 0;
$final_body = '';
/** my extra code **/
/** Set your mailing list variables here **/
$divert_email = 'trashcan@mydomain'; // The e-mail address you want duplicate messages diverted to
$teststring = 'Footer'; // The string your mailing list adds to every message body
$testst=substr($body,-160); //check only last 160 characters of message body
if (strpos($testst,$teststring)) {
$to_email = $divert_email;
} // string found; divert
else {
$to_email = $list_email;
} // string not found; send to list
/** end of my code
many lines unaltered
and the last line **/
/** original code send_email($from, $list_email, $subject, $final_body, $header); **/
send_email($from, $to_email, $subject, $final_body, $header);
