hi,

If your server is sending spam, most likely you've already ended up on an RBL blacklist.

Make sure that you have a send limit enabled, Check /etc/virtual/usage to see which User has a higher-than-average bytes log. If any User stands out, then they're likely it.

If you have the latest exim.pl, and DA 1.41.1 or newer, you should be able to log into DA as that User, and go to:
User Level -> E-Mail Accounts -> E-Mail Usage
