[Mailman-Users] Mailman performance

[Blatter, Nicholas]

Hello,

I'm using Mailman 2.1.5 and Postfix to manage a small (~500) member list
and I recently went through and removed everyone from the list, and then
added them back in. After doing so I was watching the progress of
sending the Welcome message, and noticed that Mailman is taking an
exceptionally long time to send the messages out.

It looks like the messages are getting stuck in the qfiles/out
directory, and the smtp log shows many of the following entries:

Oct 19 17:30:12 2006 (2411) <mailman.25.1161298522.9123.undergrad at x.edu>
smtp for 1 recips, completed in 80.170 seconds

Every message is taking almost exactly 80.1 seconds, with no derivation.
Postfix's mailq is empty, and all other mail is getting through just
fine.

Anyone have any suggestions?  Why is it taking so long for it to send
each message?

Thanks!
