idesign Posted November 23, 2006 Share Posted November 23, 2006 Happy Thanksgiving! I am the server administrator for a small hosting company and recently our server, 184.108.40.206, has been listed on SpamCop's blacklist serveral times over the last couple weeks. I have taken several steps to secure the mail server, Running Mail Enable software, but I am still seeing spam sent out and we are still getting listed. I believe the problem is a trojan sending out mail but was looking for any other info or advice the community can provide. My reason to belive it is a trojan is because sample spam I am seeing sent is not coming from any customers on the server and I can't find a history of it in the SMTP activity logs. I am using SPF, relays are closed, Reverse DNS lookups, and authenticated senders must be sending from a valid domain. The amount of junk mail coming from the server has been greatly reduced but I am still having problems being listed... I am in the process of changing passwords and setting up a firewall (I know a firewall should have always been there... I am new to this and trying my best to learn). Any other advice, suggestions is greatly appreciated. I fully support what SpamCop is doing and I hate that I may inadvertently be contributing to spam!!!! Thanks in advance!
