Hi! You might find this Perl script I wrote useful. It monitors courier's maillog in real time (requires File::Tail from CPAN), and when this typical TLS failure occurs, adds an exception for the misconfigured domain to esmtproutes, e.g.: bad-tls-domain.com:/SECURITY=NONE During the next retry the original message should go through because STARTTLS won't be attempted. The script also sends a notification about the problem to the postmaster of that domain (if that mail bounces to you, you could report the domain to "RFC Ignorant" postmaster blacklist: http://www.rfc-ignorant.org/tools/submit_form.php?table=postmaster). Note: you have to customize the script a bit - change your own postmaster address (the $our_postmaster variable) and change the message template (it currently contains my own signature). I'm running this script since 2005 and I've already got 290 domains in /etc/courier/esmtproutes. -- Best Regards, Aleksander Adamowski GG#: 274614 ICQ UIN: 19780575 http://olo.org.pl -- Aleksander Adamowski Administrator systemów korporacyjnych; Instruktor Altkom Akademia S.A. http://www.altkom.pl Warszawa, ul.
