Mark, I've snipped your message, but it brings up something that is a
problem for us, and maybe "hijacking" your note with a "feature

We have a pattern of having list subscribers set themselves nomail,
and sometime later, close out the ISP account that was used to receive
mail.  We would like to be able to cull out these "moved/left no
address" subscribers.  

Evidently, 2.1.11 will allow me to more-or-less identify those
accounts by telling me which accounts bounced the monthly reminder
e-mail.  It is not too great a task to look at perhaps ten accounts
per month and correlate "nomail by user" with the bounce message.

Over time, dead accounts add up.  Last time I did something about
this, I set all the "nomail" accounts to receive mail, and the bounce
processor killed off close to half the accounts.  This was after eight
years of running.  The problem with that was that I had a hundred or
so users who were still active but who did not want to receive list
mail.  (Many were following the list through reading the archives).

I'm also concerned about this proposed scheme to discontinue montnly
mailings.  It most definitely needs some mechanism whereby a user can
reset or re-obtain their password without moderator intervention.  Our
user base is just plain not password-savvy, and I'm concerned about
the increase in moderator workload if the recovery method is similar
to password resetting by root (the Unix method).
