Look at your MTA logs. They should show you when a given message comes in for a given user, and when that is successfully transmitted. I'd be willing to bet you're waiting on DNS timeouts at the remote end for one or more of your users -- their MTA is slowing you down, maybe as a result of trying to do a reverse DNS lookup on your IP address. If you haven't already enabled it, try turning on full personalization, so that you send a unique copy of the message to each recipient. For each recipient, look at the date/time stamp of when the message goes into Exim and when Exim says that the remote end has accepted the message. That should tell you where things are slowing down. Maybe it's not a DNS timeout, maybe it's a timeout of some other sort. Maybe it's a result of doing anti-spam/anti-virus processing on inbound as well as outbound e-mail. Maybe their mail servers are just very slow. But at least you should know where the slowdown is coming from. You may also be able to turn on some increased parallelism in the delivery process, so that other recipients can be handled while you're waiting on the slower sites to respond. But I wouldn't feel bad at getting everything out in 30 seconds. -- Brad Knowles <[EMAIL PROTECTED]>, Consultant & Author LinkedIn Profile: <http://tinyurl.com/y8kpxu> Slides from Invited Talks: <http://tinyurl.com/tj6q4> ------------------------------------------------------ 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
