Hi there, I was wondering if anyone could tell me how to set up a spam filter rule that will stop messages coming in that contain no content. I get several emails a day from email adresses that make no sence, with the subject relating to security hardware such are norton for example.
There is no content in the main body of the text and the email adresses that they are sent from are always different.
Any tips or if anyone could tell me what to put in the rule section of spam protection would be great,
Many thanks!
