I installed Zimbra OSS on my machine, and did a few tests that should have triggered Spamassasin and ClamAv:

  1. Sent myself a message containing "v1agra v1agra";
  2. Sent myself a mail with the "I luv you" code as an attachment, complete with .vbs extension.

The messages went through undisturbed, and the Server Statistics (anti-spam, anti-virus activity) did not register any spam nor virus hits.

I've turned on the debug logging in amavis, and looked at zimbra.log, but no activity there neither.

All services are working properly.

Is there any config files I should look at to enable SA and ClamAv?

Thanks for your help.
