[SOLVED] CBL Keeps Listing
I am using the latest version of Plesk with my CentOS server. For some reason, CBL keeps listing my server's IP address. I made the open relay tests, no problem with that. I checked the server for rootkits, also no problem with that. After reading the documentation, I learnt that CBL is not listing for relay problems but spam sending proxies or trojans. I checked the email logs and found only two non-existant domain emails which are from watchdog from the email address of "watchdog(at)companyname.localdomain". And the rest seems as valid addresses and real emails. I am not sure if they will add me to the list for these two emails.
I have to look for the other possibilities. What else may cause the problem? And how to detect it?
I'll appreciate any help.
