I have probably received close to two dozen of these messages from "US NMA" in
the past week or two. It appears that the subject line does not change, so I
think your solution is valid. I'm also seeing other spam recently that appears
to be sent by senders with valid e-mail addresses and which respond to
challenge messages.
I'm thinking of abandoning the reply function and requiring senders to visit
the web site to validate with a URL instead.

Subject: 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)

[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

Keith
