Last night one of our majordomos got caught in a kind of mailloop, when someone tried to query majordomo using a sending address serviced by an autoresponder.
Each Email hitting said account would trigger one of these We-will-answer-your-email-later messages, which caused majordomo to send its helpfile once again, which would trigger....
3000 Mails and 30 MB later I stopped the loop using the Mailservers AccessDB.
We use Majordomo 1.94.5 and sendmail 8.12.9/8.12.8
I am wondering if there is anything to avoid this situation?
Things I thought about:
Giving majordomos outgoing administrative mails a reply-to header pointing to majordomo-owner(I do not like that, for quite a few mailinglists are open+confirmed and half of the confirmation mails will then go to majordomo-owner)
Incorporate another sanity-check, so mails with
in their headers, do not get processed.
It would be nice if majordomo could act similar to a (wellbehaved) vacation, sending out a Maximum of X messages to a single recipient and resetting the counter every hour or so.
(All this should only affect the majordomo results mails, not the list traffic)
Thank you for your input.
