Hello,
We've been getting many many strange mailman-bounces. It seems that somewhere the mailman-bounces address is mis-configured. It should be mailman-bounces@music.columbia.edu, but mail seems to be sent as mailman-bounces@music.columbia.ed (note missing "u"). That's causing bounces to bounce all over the place...in our mail log we get messages like:
Jul 19 12:02:50 roar postfix/smtp[18535]: 9F86883BE24: to=mailman-bounces@music.columbia.ed, relay=none, delay=0, status=bounced (Host or domain name not found. Name service error for name=music.columbia.ed type=A: Host not found)
but also:
Jul 19 12:02:54 roar postfix/qmgr[10647]: E969F83BE2C: from=mailman-bounces@music.columbia.edu, size=4419, nrcpt=1 (queue active)
So both the correct address and the incorrect address are being used...I've poked around in all of our configs and I can't find the incorrect address anywhere. My suspicion at this point is that there's a virus somewhere on a users computer that is propagating the incorrect address and that many of the messages are the result of spoofed mail. Can anyone help me to understand what's going on? Or suggest where I might look to see if the mailman-bounces address is in fact mis-configured? In mm_cfg.py we have:
mm_cfg.py:DEFAULT_EMAIL_HOST = 'music.columbia.edu' mm_cfg.py:DEFAULT_URL_HOST = 'music.columbia.edu'
so that seems correct...
thanks, douglas
