On the relatively small [850 subscribers] list Travel-L, I have set Renewal= 4-monthly to roughly match an academic year cut up Sep-Dec, Jan-Apr, May-Aug. If I set a problem account to nomail, at worst it will clutter up the subscriber list for 4 months. Perhaps this is wasteful of the disk resources used for the list, but I see a lot of transient errors that are, and "host unknown" that becomes "known" again within a few weeks. Having renewal/confirmation 3 times a year, plus the monitoring report and auto-delete has made my life as an owner/manager much, much easier. However, my experience running travel-L has only been about 1 year so I have a lot to learn--like how to find a replacement :-) *---------------------------------+-----------------------------------* | James A.
