I've seen it happen using md_check_against_smtp_server in filter_recipient(). If the downstream SMTP server is down or returns a tempfail, then filter_recipient() will too (assuming you are using the sample code from the man page).

Re: [Mimedefang] action_tempfail and delete_recipient question
Thanks for Kelson's help but I still have a few questions:

1. Does action_tempfail affects all recipients?
Yes.
How can I only tempfail 2 of 5 recipients then? Is stream_by_recipient the
right approach or I can hold them in @tempfail, tempfail them at the end of
filter_begin. If the second approach should work, do I need to
delete_recipient them all so they won't receive the message
since @Recipients is global?
Please bear with me if I am confused.
Thanks.
Xiaoyan
2. Is delete_recipient needed? If not, wouldn't tempfailed recipient
receive a copy of the message?
No, and no.
foreach $recip (@Recipients) {
if (should_greylist($sender, $recip)) {
md_syslog('warning', Filter Recipient:$sender:$recip);
#delete_recipient($recip);
return action_tempfail(Tempfailed as anti-spam
measure. Please try again.);
delete_recipient($recip);
}
}
Remember, any time you call return, it'll stop processing the
subroutine. So in this case, it will *never* call delete_recipient, and it
will only run up to the first recipient that triggers should_greylist().

RE: [Mimedefang] action_tempfail and delete_recipient question
Mathew: Thank you for your reply. The reason I want to move it to filter_begin is that some MTAs don't handle tempfail at RCPT TO stage correctly. They bounce the message instead of requeue. A few people on the list had shared their experience and I have run into the same situation as well.

(response - 2xx [OK] or 4xx [tempfail] or 5xx [permfail]) You probably need to tempfail each recipient at the time of the RCPT command, rather than gathering all the recipients as you do below. In other words, SMTP does not allow a RCPT TO: [EMAIL PROTECTED] RCPT CC: [EMAIL PROTECTED] RCPT TO: [EMAIL PROTECTED] 2xx [EMAIL PROTECTED] OK 4xx [EMAIL PROTECTED] tempfailed anti-spam try again 5xx [EMAIL PROTECTED] no such user ___ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
