Sys Info:
majordomo_version = "1.94.4"
Sendmail 8.9.3/8.9.3
perl-5.00503-12
RedHat Linux 6.2
I don't use majordomo for lists, but only for the
autoreply function. I have several aliases set up in /etc/aliases that
send the "sender" an autoreply message, and the original mail is sent to a real
e-mail address for manual response.
For example, if someone sends mail to sales@blah.com, the sender would receive an
automated reply that has relevant info on who to call, etc., for sales info, and
the original e-mail message is sent to an actual sales person's e-mail
address.
Recently, spammers have begun sending e-mail to sales@blah.com and in their reply-to
(Mail-From) they also have it configured as if it were coming from sales@blah.com. So, my server receives a
mail from sales@blah.com which is addressed
to sales@blah.com. This obviously
creates a massive loop, while my server keeps autoresponding to itself, and the
sales person's mailbox gets filled with thousands of the autoresponder message,
eventually leading to the crashing of my mail server(s), if not caught in
time.
How can I stop this from happening? Would I
use the $global_taboo_headers section of majordomo.cf? If so, what is the
correct syntax to prevent mail being sent from the majordomo sales
alias address?
Reading through the archives, I think I found the
right syntax, but cannot be sure. Would this work?:
/^from:sales\@blah\.com/i
OR
/^from:\s.*sales@blah\.com/i
I have seen several variants in the archives, but
can't determine which one is best to use. Since the looping causes such
major problems, I'm afraid to test either until I have some sort of guidance
from the list. If neither situation would work, does anyone have another
suggestion to try?
Thanks,
Steve
