I'm trying to make a mail filter that filters e-mails from [email protected] .. However, sometimes his e-mails come from [email protected] or [email protected] . And sometimes he sends e-mails from [email protected].

So I'm trying to use regular expressions to solve my problem.

So far this is what I have:
^drew@buffalobills\.com|.*bufalobills\.com|nfl\.com


This filter is catching [email protected] and I don't want it to. Is anyone here good at regular expressions and able to help me? I'm completely L_O_S_T.
