It has the merit to be compact but the inconvenient to read the body.
I use the followings procmail rules:


:0:
*> 100000
*^subject: (undeliverable |undelivered |returned )*(mail|message)(:* (returned to (mail|send)er|user unknown))*
swen-junk

:0:
*> 100000
*^subject: (new(est)* |latest |last |current )*(net(work)* |microsoft |internet )*(critical |security )*(pack|patch|update|upgrade)
swen-junk

:0:
*> 100000
*^subject: (abort|bug|error|failure)* *(advice|announcement|letter|message|notice|report)
swen-junk

This catch all swen mails except those with no subject. It would be easy
to add them (*^Subject: *$) but I let them to spamassassin because I
want to avoid false positive (I will try the body check for them).
Of course my size test could be improved.
