Re: Monitoring for Spam Listings

My message was more cryptic "554 Your access to this mail system has
been rejected due to the sending MTA's poor reputation. If you believe
that this failure is in error, please contact the intended recipient
via alternate means."

But that is how I tracked it down. Someone must have just upgraded a
spam filter and we got notice.

it, it likely doesn't merit much worry.

Well, not hearing about it might just mean that people aren't even aware that they are supposed to be getting mail.

There have been a number of occasions when I noticed a list subscriber posting a valid message to one of my lists and my mail server found the address in one of the RBL's it uses.

The person sending the post was totally unaware that their mail server had been listed in a RBL.

FWIW: When my mail server rejects a message because of RBL, it sends a message something like "Rejected - see http://www.spamhaus.org/query/bl?ip=151.33.29.133 - questions: david at fallingrock.net". Spammers ignore the message, humans don't.
