Is it possible to tell Mailman to send outgoing mail for a mailing list in several separate batches? My mailer (Exim) delivers a message for multiple recipients sequentially. Of course, this is more efficient in terms of network usage, but processing several batches in parallel is faster (and network bandwidth isn't an issue here).
In addition, administrative requests are not handled until the cron/qrunner script is run---I'd prefer if they were dealt with immediately.
Did I miss some config options? I'm running Mailman 2.0.1.

We haven't yet tried this on the machine running Mailman (because those lists don't fit the pattern of being large lists with addresses on lots of domains)...for the machine running Majordomo on a large list, adjusting the Exim configuration dramatically improved delivery time. You might also want to adjust the time Exim is willing to wait for a response from an SMTP server...we had left that at its default setting (which is to use the host system's timeout...that timeout jumped hugely either in an update of Linux or in the earlier switch from BSDi Unix to Linux. The combination of the two Exim adjustments reduced the first pass time through the list from well over 24 hours down to around 2 1/2 hours.
