Try this: remove the filter completely and close the list of filters. 
Then, reopen the list and create a new filter, giving it a different 
name and typing in the email address from scratch instead of using 
Copy/Paste.  It sounds a tad heavy-handed, but there's a possibility 
that there's a non-printing character stuck in there that's fscking 
things up.

Back when I did Windows support for an ISP, there were times that simply 
removing and replacing the user's password for Dial-Up didn't work. 
Having the caller use the Backspace key to remove the password and 
holding it down for at least a second after the box was cleared did. 
No, I don't know if there were invisible characters there, but it's as 
good an explanation as any.
