procmail recipe not working

[dman <dsh8290@rit.edu>]

I've been getting a bunch of spam on a certain list.  The latest
message has the following From: line :

 From: "Lisa J." <8102239.27@reply.pm0.net>

(some have a different name, but the same address)  I want to
automatically file these in the bit-bucket.  Should be
straightforward, right?  In my .procmailrc I have the following :

:0
* ^From:.*reply.pm0.net
/dev/null

:0
* ^From.*8102239.2[67]@reply.pm0.net
/dev/null

:0
* ^From:.*8102239.27@reply.pm0.net
/dev/null


However the messages keep getting past these recipes and to my
list-matching recipe.

Any clues?

TIA,
-D
