How to prevent spam from my own server?

[santibm]

Hi,

I have a server with directadmin, exim 4.63 and Spamblocker 2.1, everything works quite well, loads of spam are cached on their way to the mailboxes. But also some of it makes it trough, I wonder how I could prevent spam messages coming from our own addresses as on one side spamassassin marks it with a lot of points but at the end the user is in the whitelist and the spam reaches the mailbox.

Thanks for any suggestion!

Why is the username in the whitelist? Is the spam coming from your server or are addresses on your server being faked?

If spam is coming from your server you should probably turn off the accounts doing the sending if your Terms of Service allow. If not, change your Terms of Service.
