I used to have issues with this, but my solution was to turn on dummynet (http://cs.baylor.edu/~donahoo/tools/dummy/) on my firewall and limit SMTP to use half of my outbound bandwidth (I get 256kbps, SMTP gets 128kbps of that). Interactive sessions are a lot more pleasant to work with now. I know a lot more about Windows SMTP server than Postfix, but outbound delivery rate on machines is generally limited by the number of io's per second that a disk can do. If you want to saturate a fast link with small messages you'll probably need to stripe your queue/spool directory across multiple disks. Performance on the Windows SMTP stack will also greatly improve if you increase the rcpt to batching that Mailman uses. On many Unix MTAs that will slow you down, because the MTA can't send the same message to multiple destinations at the same time. My Mailman configuration uses Unix for running Mailman, and Windows 2000 SMTP Server for outbound email. I doubt many (if any) other people are using this configuration, but if people are interested in more detail on configuring Windows 2000 SMTP for maximum performance I can help out quite a bit. alex ------------------------------------------------------ Mailman-Users maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users
