Each day listed to SPAM database

[seotraffic]

I have a server where I keep my websites.

One day I found that the website cant send forum activation emails.

After a quick search I found that servers ips are listed in Spam database. For example mine:

http://cbl.abuseat.org/lookup.cgi?ip=82.78.216.197


The main problem is that I do not send spam, and even after I delist the server IP, it get back listed after 3-5 hours.

Something(script or virus)/someone ( hacker) is sending emails from my server and I dont know how to be able to control to see who did that.

I am using a FEDORA server + Pleask and I want to be able to see what emails and to who / are sent.


IS there a way to see that?

How can I secure my server? I scanned the server with antivirus and found 0 viruses.

I am completely blind

You need to watch logs, you need to change settings and hunt down the problem.
Maybe is only a missconfiguration ...
