Unidentified subject!

Procmailers,

I have been receiving an increasing amount of unsolicited email with
the From field containing all numbers before the '@', example:

   From: 03195750(_at_)msn(_dot_)com

I tried to puzzle out the regular expression syntax but could not find a
way to detect 'everything between From: and @ is all numbers'

Any assistance greatly appreciated!
