[Mailman-Users] mailman not posting (using postfix w/ RH 8)

[Paul Daniel]

Greetings:  I have installed mailman 2.1.1 on RedHat 8.0 with python 2.2.2 and
postfix 2.0.2.  The install seemed to go well but the posting is not working:

symptoms:
- list administrators are not notified when a list has been created
- list administrators are able to administrer their lists using the web
- list members may post messages - and the messages are properly archived
- non-list members may not post messages but nobody gets a bounced message
- list members never receive any posted messages

what i've checked:

- <path to mm>/bin/check_perms is ok
- crontab was created as 'root' with <path to mm>/bin/cron> crontab -u mailman
crontab.in 
- aliases and aliases.db are up to date; postfix knows where to find them
and has reloaded them several times
- not using smrsh with postfix
- nothing of note in <path to mm>/locks | logs
- postfix on this host can deliver mail (otherwise you wouldn't receive this)

thanks in advance
