Help: Hundreds of Outgoing Spam Messages - How to Stop ???

hi there,

my host blocked my email port because it says there are hundreds of outgoing messages in very short period of time.

i am not much of a technical person so I am still not sure where to start or what is causing the problem. Following is the maillog

Can anyone help me sort out the issue?


I’m learning about server administration with virtualmin and maybe we can elucidade some issues :slight_smile:

  1. Is it possible that your server is open, as a relay? (Check at under SMTP test)

  2. Are you using a firewall like CSF?

  3. Is any domain of the email listes in your log hosted on your server?
