Another quick question, Ive always had problems with outgoing email servers in Linux being attacked from the outside. lol, laugh, i do, as my ISP warned me about 500 emails per month being spammed all over the place from my domains that are hosted on my cluster. What i found is that people were using my email server (SMTP) to send out these emails without me knowing lol, typical noob i know, but Linux is not my fortay & with Windows its simple to lock down, against this. At the moment my setup is CentOS 5.4 with ISPconfig 2.2.35, using Postfix and before I open up my firewalls i want to make sure i can try and keep the outgoing mail service locked down. So if anyone can suggest some security measures i can take or any configuration changes i can do it would be most appreciated. How do i check to see if Relay is enabled or disabled? How can i monitor the outgoing emails in realtime? Thanks people for any help on this subject, and stop laughing, lmao.
