I have SpamAssassin turned on and using RBL in the WHM control panel using the lists from spamhaus. However, these type of e-mails are getting in. Are there any ways to stop them?
Example of the e-mails I have been getting: http://i48.tinypic.com/i6j8jr.png
Would it be possible to use SpamAssassin to block links with the word unsubscribe in them?
EDIT: Are there any custom and more advanced SpamAssassin rulesets that can be downloaded and used?
