This won't help. Looking at the mail server logs shows that most of the
affected users are getting auto-deleted from the list because the receiving
site returns a 550 (no such user) error code during the SMTP transaction/
delivery attempt. SMTP error codes are intended to be 'definitive' and
LISTSERV does not attempt to 'second-guess' them.

LISTSERV has 2 alternate criteria for determining when to delete. The first
criteria is total number of (permanent) bounce errors (all temporary error
bounce codes are discarded). The second criteria is a pattern of repeated
bounces over some period of time. For WIN-HOME these are criteria are Max
50 bounces and/or bounce every day for 4 days.
The fact always is that if your ISP/mail system responds to sending SMTP
servers that your email address does not exist, when in fact it does, then
you will likely not receive some legitimate mail, not only List mail, but
other mail. As a user of that mail system you probably should be concerned
about this enough to let your ISP/mail system admins know how you feel about
that.
