Match Style *not* Equal ?

Periodically I get emails that appear to have the “To” field spoofed. No one that legitimately sends me email ever messes with the display of my address so I think I want to add a rule to my BlockList that blocks messages that do not contain my email address displayed in the “To” field.

When I went to add a rule to the Blocklist I noticed that there isn’t a “not Equal” match style. I suppose I could negate the regular expression, or is there a better way?

Are you sure? I get lots of legitimate messages (especially mailing list and computer-generated ones) that do not have my address in the To field. Plus, what happens if you get a Cc?

If this is what you want to do, a regular expression is the way.
