As I mentioned, this looks very promising if we should decide to pursue it, but I’m a bit confused about the definition of the DEL_FILTER entry point.
The Advanced Topics Manual for LISTSERV 17.0, Section 4.2 List Exit Points, sub para 4.2.2 DELETE/SIGNOFF/CHANGE Entry Points, under Name: DEL_FILTER says: "Description: This exit point is called for all SIGNOFF commands, and for DELETE commands issued by a registered Node Administrator. It is NOT called for DELETE commands originating from the list owner”.
When a user tries to unsubscribe, does that use the SIGNOFF command? I’ve looked in the User (sorry, List Subscribers) Manual and List Admin (List Owner’s) Manual, and don’t see the email command for a user to unsubscribe themself from a list. I’ve always used delete, but that’s as an admin, I can’t say that I’ve used email to unsubscribe myself from a list...
Presumable, the Web Interface would use the same code, just generate the same params as the mail interface uses, so that would also use SIGNOFF, rather than DELETE?

These are all administrative lists and are used only for important messages we want to be sure that faculty, staff, and/or students get all of these messages. In our case, we use a PERL script that we got from a former frequent poster to this list who has since retired.

So subscribers can't unsubscribe themselves anymore. This also blocks listowners from making changes, so choose the right time to lock the list. When a user sends an unsubscribe mail to the list they will receive this message:
