I find it
difficult to distinguish some cctalk messages from spam.
The From: could be anyone, and the Subject: is not always technical
enough to recognize. Could your mailer add '[cctalk]' to every
subject, if it is not already there? This would also enable a filter
to send the message to a cctalk folder. It's a technique that I have
seen with other e-mail lists, and I like it.
You can filter off of one of the mail headers, like for example:
List-Id: "General Discussion: On-Topic and Off-Topic Posts"
<cctalk.classiccmp.org>
or perhaps this one:
Return-path: <cctalk-bounces at classiccmp.org>
