For everyone using the Clamav plug-in, I would suggest trying the Sanesecurity 3rd party Clamav signatures to filter out spam.
Details on how to install it can be found at this link:
Please note that in OS X that you have to put “sh” before a script to initiate it. Also, with my install, the clam sigs were in the following directory:
I have script 2 from Bill Landry running on an hourly basis for updates (along with the clamav default updates), and the Sanesecurity signatures have been catching a high number of spam. I set the LogFile to /var/log/clamd.log in clamd.conf at /usr/local/clamav/etc/clamd.conf, so I could easily view the results through the Console.
I run Clamav before Spamassassin, so the load on Spamassassin has also been decreased. I’ve been noting errors with Spamassassin when it’s overloaded, so having Clamav filter out emails first will help maintain Spamassassins reliability for me.
