Hello Admin, currently spam show up in inbox mail as [SPAM] and I have to delete them manually...
To prevent spam (in addition to the SpamAssassin default score of 5), I would like to create a list of blocked senders and also automatically delete incoming mail that contain specifics words in the content. Should I configure SpamAssassin? Do you know any tutorials?
How to add rules only once and apply them for ALL users and domains on the server?
Thank you!
