One mail account of many is accumulating many bounce messages 1000’s per hour.
I’m surprised that so many mailservers out there are bouncing mails, reporting them as Spam or defective in some way. I thought it better to just dump them.
I am presuming the original mails are sent spoofing the mail account on my box. Although they don’t complain about DKIM being wrong, so maybe they are originating from my box?
I have shutdown any clients for the account that might have been hacked. I’m not sure if the miab is being used as an open relay, as I can’t find any bounce messages that say the DKIM was OK (although I thought I had seen this earlier)
Please any suggestions on how to make MIAB suspend a user account, and also how to figure out what is going on.
