set-spam

Change the spam and virus scanners for all domains

By default, Virtualmin uses the stand-alone ClamAV and SpamAssassin programs for virus and spam scanning, named clamscan and spamassassin respectively. However, on a system that receives a large amount of email, running these programs for each incoming message can generate significant CPU load.

This command can tell Virtualmin to use the background scanning daemons clamd and spamd instead, which are faster but consume additional memory as then run all the time. To enable the ClamAV server, run it like so:

virtualmin set-spam --enable-clamd
virtualmin set-spam --use-clamdscan

To enable and use the SpamAssassin daemon process, run the commands:

virtualmin set-spam --enable-spamd
virtualmin set-spam --use-spamc

However, using spamc makes it impossible to have separate per-domain SpamAssassin configurations in Virtualmin.
