Often true, but the subject of this thread included "personalized footers" which require sending separately to each recipient. Also, what should be of concern is not only the time to deliver all the messages from Mailman to the MTA, but also the total time from the start of Mailman's delivery to the MTA until the MTA has finished delivering to the recipient's MXs. I suspect this latter time is not so dramatically impacted by Mailman's VERP or personalization. -- Mark Sapiro The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

Worth noting, Mailman is a lot faster if you don't send to 1 at a time. If they're all at the same domain, like our mass mail to staff and students, it is really fast: smtp to for 25570 recips, completed in 39.777 seconds smtp to for 41153 recips, completed in 84.754 seconds Even if they are at many different domains it does well: smtp to for 2016 recips, completed in 158.363 seconds smtp to for 2199 recips, completed in 701.392 seconds Joseph Brennan Manager, Email and Systems Applications Columbia University Information Technology -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
