[Mailman-Users] Upgrade 2.0->2.1 no control messages

[Ryan K. Brooks]

I've completed my upgrade to 2.1 (which, btw, is absolutely awesome), but
I'm having one problem:

- Outbound "control" messages like: Subscription notices, Lost password
reminders, invites, etc. don't ever appear for the recipient, even on
local accounts.   Admin, moderator, list traffic, etc. all get delivered
just fine.

This is on a FreeBSD 4.6 intel machine, running sendmail as it's
MTA.  Python is up to date.   No error messages are appearing in the logs.

Thank you for any tips!

Also, it is still necessary to have a second sendmail running on a unique
port to prevent the queue from stalling?

Thanks!

Ryan
