We have launched SpamAssassin as an installable app from Webuzo.
Just search for SpamAssassin in the left hand side search bar in the EndUser Panel.
All configuration with Exim will be handled by the installation script.
Emails that are categorized as SPAM will be bounced back to the sender with a message that their Email has been categorized as SPAM.*
You can whitelist email address which maybe false positives and blacklist the ones that may not be categorized as SPAM.*
From now your Email Experience will be SPAM free in Webuzo.
*Currently no option is provided from Webuzo you will have to change these settings via SSH.
