[Mailman-Users] Messages not posting

[Angelo Bonadonna]

Hi--I've got what seems to be a common problem:  Everything seems to be working fine, but messages won't get sent--and there are no error messages (in mailman/logs or /var/log/maillog).  I'm pretty sure the aliases, wrapper, etc. are all correct and in working order.

There are files in mailman/qfiles. I checked to be sure crontab was installed.  /var/log/maillog says the mail was sent.  (BTW: is there anyway to manually send queued messages?)

Here's my configuation

Mailman 2.0.3
Python 2.0
Sendmail: 8.9
Redhat Linux 6.0

(Note:  I've gotten this same set of versions of software to work on a backup box I experiment with.  I'm pretty convinced I have a sendmail problem, though I don't know what it could be.  Sendmail is indeed functioning for _most_ of its other purposes.  It works fine, e.g., in sending list creation and subscription notices.)  Help!  Angelo
