I have installed mailman on RedHat 9, mailman version is 2.1.1, and postfix
version 2.0.10 using mysql lookups...
When I try to send an email to a group (of about 75 or more people (yet to
find size limit)), The email appears in the archive, but never gets
delivered to any of the list members.
First (and most important) read the README.POSTFIX on your system and
follow the advice there on integrating Postfix with Mailman.
If that does not solve it then look at your Delivery Defaults used in
~mailman/Mailman/mm_cfg.py (and Defaults.py)
DELIVERY_MODULE = 'SMTPDirect'
MTA = 'Manual'
