Happy Thanksgiving! I am the server administrator for a small hosting company and rec ently our server, 188.8.131.52, 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, b ut I am still seeing spam sent out and we are still getting listed. We use Qmail with spamcontrol patch. Our relays are closed, we have 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... 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!
