Avalanche of SPAM

Hi. Here are a few excerpts from my incoming log - tmda 
1.0.3.

Date: Sat Jul 7 05:09:40 BST 2007
From: US NMA <[email protected]>
   To: [email protected]
Subj: The United States National Medical Association
Actn: DELIVER (headers-file 
/home/keith/.tmda/filters/subject_reject 
[email protected])(6148)

Date: Sat Jul 7 05:09:44 BST 2007
From: US NMA <[email protected]>
   To: [email protected]
Subj: The United States National Medical Association
Actn: DELIVER (headers-file 
/home/keith/.tmda/filters/subject_reject 
[email protected])(6147)

Date: Sat Jul 7 05:09:46 BST 2007
From: US NMA <[email protected]>
   To: [email protected]
Subj: The United States National Medical Association
Actn: DELIVER (headers-file 
/home/keith/.tmda/filters/subject_reject 
[email protected])(6135)

Anyone else getting this avalanche? My solution was to add 
the following line to my incoming filter file, after 
checking for mail I want to accept:

# unacceptable regex matches for Subject: mail header field
headers-file ~/.tmda/filters/subject_reject
[email protected]

and in the subject_reject file add the following regex line 
to match:

"The United States National Medical Association"

It seems that blocking spam on the From: address hardly 
works, as the from address keeps changing, whereas the 
subject line is alot more constant.

HTH

Regards

Keith
