garyttu Posted August 30, 2007 Share Posted August 30, 2007 All, Our Mail server is being blocked by SPAMCop- the IP report only says SpamTraps are being hit, no reports. I have: - Restricted all outbound port 25 traffic except from the mailserver - Scanned the mailserver using SAV Corporate and found no virus/trojan issues - Made sure we are no relaying Anyone have any ideas as to what might be causing this problem? Reading the FAQ, I see it could be auto responders, but i'm not sure how I should check that. Does this mean I need to turn off Out of Office and NDRs permanently?
