Hi Bryan,

I've encountered something similar when there is a problem with the Outgoing qrunner (it's behind, a disk is over quota, sendmail -- which we use for the MTA layer -- is throwing an error, the list has gotten tagged by the spam filter, etc).  How do your queues look?

If the posts that aren't received are all From: yahoo.com and aol.com
addresses, DMARC is the likely reason. See the FAQs at
<http://wiki.list.org/x/17891458> and <http://wiki.list.org/x/17891477>.

On the other hand, if this is independent of sender, see the FAQs at
<http://wiki.list.org/x/4030723> and <http://wiki.list.org/x/4030690>.

Does Mailman record bounces for the undelivered mail? See Mailman's
'bounce' and 'error' logs if you have access.
