I was surprised to find that Listserv apparently does not have a set of content_filters set up, and the filter system appears to be fairly basic. I'm in the process of converting some content filters from Majordomo to Listserv, but does anyone have a set of suggested content filters they'd be willing to share? Here's what I'm starting with: Subject: subscribe Subject: unsubscribe Subject: uns*b Subject: un-sub Subject: help Subject: change*address Subject: request*addition Subject: cancel Action: REJECT Subject contains 'cancel', 'subscribe', 'unsubscribe' or other words that indicate an administrative message.
