One benefit to using Exchange 2000 as your outbound MTA is that it works very well with batching. I have my Exchange setup to allow 500 recipients per message. Mailman is also configured to send 500 recipients per message. As a result all 55 aol.com, 65 yahoo.com, or 51 hotmail.com recipients on my largest list are send to Exchange on the same message. Exchange can send a single message to handle all of those recipients instead of sending 5 or 10 as would occur when using the recommended batching of 10 recipients per message for postfix and other popular Unix-based MTAs. Exchange 2000 has no problem sending the same message to multiple domains at the same time. The remote deliver agent on most Unix MTAs can only send to one domain at a time so if you set the batching to 500 then you single thread your delivery and it can take forever for messages to get out. Note that you can use Windows 2000 SMTP server instead of Exchange for this. The code is exactly the same, Windows 2000 is just missing other parts of the mail system and some of the administrative tools. I talked to Ralf offline about his comments yesterday. All of the issues that he brought up were about Exchange 5.5. Exchange 2000 replaced that with a much newer MTA almost three years ago. alex ------------------------------------------------------ Mailman-Users mailing list [EMAIL PROTECTED] 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/ This message was sent to: archive@jab.org Unsubscribe or change your options at http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
