Hello fellow RT users,
We recently installed the CommandByMail perl module, and our developers were happy, as it would cut down on their workflow time (rather than going to the web tool).
However, a little over a day later, we suddenly got hit with what ended up being over 100k emails - which seemed to be bounces sent by our RT box to our mailing lists box, to our main mail server box, then back over to our RT box, which should have stopped forwarding the bounce mail, but it instead kept on going and we ended up with all these bounce emails:

RT thinks this message may be a bounce
I read on a blog that had some info on how to configure the CommandByMail (on cpan the install instructions were actually a broken link), a comment in passing about people being able to spoof emails once the CommandByMail is used; not sure if that might be related, but we ultimately think that we may have been getting mail bomb attempts, which didn’t come to light until we installed this module and it allowed those through.
Or perhaps something else is going on? Anyone encountered something similar, or have an idea? I tried several searches on Google but came up snake eyes.
Currently we have mitigated the problem by REJECT’ing from the bounced senders (email@example.com, and <>), and also backing out the pm.
Thanks in advance everyone.
