Hello I have a big problem, i have a virus in my network that is sending spam. I know this because the spam is sent only from monday to friday , nothing on weekends. I'm using ispconfig 2 with suse 10. I have blocked port 25 from the network to the server, so now users have to use the SquirrelMail, but is still sending spam. The spam is sent from users that don't exist on the server, and in /var/log/mail they don't show up. the spam is sent from users like [email protected] in SquirrelMail the email address and the name can not be changed. And i do not have any php-scripts on my website everything is simple Html. And i checked my computer with rkhunter- nothing If you have any ideas please help,
Sounds like your server is being used as an open relay. Can you run an open relay test? http://www.checkor.com/
