Server Type: Server 2003 STD SP2
We Use ZoneEdit
Recently we were attacked by hacked mail servers. we got blacklisted at 3 different places tier 1. it has been about 2 days that we are no longer listed and everything has been resumed back to normal.
Except that some messages from some domain are stuck in my queue and are stuck on retry
highlighting that folder allows me to see a message that states smtp protocol error
another folder states connection was dropped by remote host
no changes where made to the configurations on the server
Most emails are being sent with out a problem.
