Filters have commonly been put in place for the From: field and using the "contains" option, which does not require the entire e-mail address.
If you are using IMAP access I'd suggest you find out how to add filters on the server side rather than in your e-mail client. Then they are "one and done" and you can change e-mail clients at will, or use multiple devices to access your e-mail, and all will have had the same filtering applied by the server before you ever see your messages.

Tolerance is the positive and cordial effort to understand another's beliefs, practices, and habits without necessarily sharing or accepting them.
