Hello there,

1) Putting the same address as both 'owner' and 'moderator' is
redundant,

I have removed email address from moderator field.

Still the mailing list moderator or owner not receiving notification email of member/non-member post to list.

2) is the list's web admin General Options -> admin_immed_notify set
to Yes?

Yes it is already set to Yes.

Do the owners/moderators receive the daily summary of outsting
requests?

No moderator does not receive any email from mailman.

I have found below logs in smtp-failure file of mailman:

Jul 08 13:15:00 2013 (26273) All recipients refused: {'all_cartesian-owner at exampledomain.com': (550, 'sorry, no mailbox here by that name. (#5.7.17)')}, msgid: <mailman.1.1373269495.26271.all_direxions

Please help me to solve this issue.
