Thanks for your entry kryptos. It will help a lot of others who ARE using 8.1 (constantly updated) but were using bulk.rhs.mailpolice.com as part of the SBLLIST.
For others who were not helping him find an answer, but just pointing out he should have upgraded a while ago, yes you are right, but why not help to resolve the issue FIRST, then chew him out for having an insecure server AFTER the fix. I am sure he, like myself would have been stressing if he was getting several hundred reject emails per hour and feeling bad because you have not updated your server when it should have been would just have been exacerbating the situation.
My mail server has been rejecting mail for over 12 hours waiting for me to have the time available to track down the issue. Thankfully, I don't use mailpolice on any of my clients SBLLIST or I would be getting a lot of angry calls.
This is the third time over the years the mail server has had issues because of RBL or SBL servers going off line. I need to find the time to look into what would be required to tell qpsmtpd to ignore a server if it fails. Any ideas Charlie? or others?
