Restrictions / Controls & Rules

I want to enable rules on the SMTP server to try and eliminate certain types of spam (this is to bolster a already in-place anti spam solution) such as mails containing the word viagra etc.

What I have noticed though if I set a rule that matches the criteria of subject or body contains the word “sex” it follows the action correctly (move to folder or reject etc)

However it also bans “essex” - this is going to cause me an issue.

Any one guide me on this?

Subject: Restrictions / Controls & Rules

I have come up with one solution.

However is seems very long winded.

Modify the rule to be when the subject contains the word Sex then another when subject does not contain the word Essex then ban.

However I would need to know all words that contain the sub-word of sex.

There must be a quicker / more efficient way???
