On September 27th, a desktop computer behind our NAT firewall was infected by a Trojan. It sent out spam and we were listed on multiple blacklists. On Monday the 29th, I identified the computer and removed the Trojan. In addition i blocked outbound port 25 from any computer other than our secured mail server.
I have requested de-listing from all of the blacklists and all but SORBS have done it quickly.
SORBS however is proving to be very problematic and unresponsive. I go on, submit for delisting and I am delisted. But, about 24 hours later, I am listed again. When I check their database it shows that I have been re-listed for the same email from Saturday the 27th!
The only place I have found to actually type text stating the circumstances and that the situation has been resolved, only sends me a ticket stating that the service is not for use of requesting delisting and has been deleted.
Any help is very much appreciated!
