[Bug 1885172] [NEW] Administrator email not delivered

Public bug reported:
We are using GNU Mailman version 2.1.18-1. This morning one of our administrators posted to our listserve as normal, but it was not received. In the archives, it is showing as delivered. We have not had any issues like this before. Suggestions on how to ensure that our emails are being posted?
** Affects: mailman Importance: Undecided Status: New

** Changed in: mailman Status: New => Incomplete

So the posted message is in the archive, but was not received by whom? By no list members on only by some?
You need to check Mailman's logs and queues and possibly the MTA logs. Possibilities include the message is still in the out queue indicating an issue with OutgoingRunner or the message is in the shunt queue in which case there will be an exception and traceback logged in Mailman's error log.
See sections 6.2, 7, 8 and 9 at https://wiki.list.org/x/4030723 for more information.

Hi Mark,
Thank you for your email. It looks like it was sent but it went into everyone's spam/junk folder. It was very odd as her email address has not had issues posting before. I will go through and check her email settings, to be sure.
