[BlueOnyx:20277] Mailman config issue

[barry mishkind]

Hello,

We recently upgraded from 5106 to 5209, and, now, none of the admin messages from Mailman go anywhere.
Neither moderator advisements nor new subscriber reports are received.

Is there a config file that might not have been found as we converted.  I know that the file /ver/spool/root/cron used
to have the actual cron for Mailman, instead of what was stated in the /etc ... files.

I did find this after telling mailman to "send this to the owner" ... 

Nov 19 21:49:09 5209r milter-greylist: uAK3n9Zw017036: skipping greylist because address 127.0.0.1 is whitelisted, (from=<broadcast-bounces@******.net>, rcpt=<broadcast-owner@******.net>, addr=localhost.localdomain[127.0.0.1]) ACL 106

Then I see:
Nov 19 21:49:10 2016 (15398) SMTP session failure: 553, 5.3.0 <mailman-bounces@*****.net>... No such user here, msgid: <mailman.0.1479613748.17033.broadcast@******.net>
Nov 19 21:49:10 2016 (15398) SMTP session failure: 553, 5.3.0 <mailman-bounces@*****.net>... No such user here, msgid: <mailman.0.1479613748.17033.broadcast@*****.net>

.. but unless there is another file, the "owner" is noted in the General setup page for each mailman list.

Suggestions?

thanks!
