That would still make it one of the larger Mailman installations I know of. > VERPing the confirmations seems to work as expectedc and I assume that > there is not much of a burden on the server without VERPing every > message or even VERPing a sample of messages. There shouldn't be a whole lot of load resulting from VERP'ing the confirmations, no. Those should be going out, at most, once per day per recipient who's been identified as needing confirmation. Even if all your lists were announce-only lists and you only got one announcement per list per month, you should probably see more "regular" traffic than the confirmations. I'm not sure, but turning on verp_confirmations may result in other list administrative functions also being VERP'ed, but again even if you put all them together, they should still be a relatively small fraction of your overall volume. Please let us know if you have any further questions, or if you'd be willing to contribute more information to be put into the FAQs. -- Brad Knowles <[EMAIL PROTECTED]> LinkedIn Profile: <http://tinyurl.com/y8kpxu> ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
