Many of the web hosting services that offer mailman place a limit on the number of messages/hour that a given domain can deliver. This is presumably done to avoid saturating their servers. If you exceed the limit, they just ignore some of the recipients. Two hosts that we use have 300 and 500 as their limits. We have several largish email lists with several hundred addresses, one of which has ~400. If several people send to one or more of these lists in a given hour or one person sends to several lists at once, some of the recipients don't get the mail intended for them.
These hosts recommend using PHPlist instead which has a feature that can control the timing of the messages so as to not exceed the list, but PHPlist doesn't work for members of the list sending mail since it is really designed to be a Newsletter distribution mechanism. Is there any feature (I found nothing in the documentation) in Mailman that would help out here, or are there people on this email list who have found encountered and solved this problem? ------------------------------------------------------ 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
