When I send an email to my Mailman mailing list address, it is getting stuck in a loop. When I send an email out, the email that is supposed to get sent to the list of subscribed people, instead it sends the email to the mailing list address, causing an infinite loop of sending the email to itself. The problem seems to have appeared for no reason (the list used to work just fine). What should I do?
end of /var/log/mail.warn: http://paste.debian.net/884140/
/var/log/mail.err is empty
EDIT: Does not seem to be an issue with Postfix, my website's contact form works just fine.
