Hi Mark,
Thanks very much for your fast response--I have a lot to learn and I really
appreciate the help.
The qfiles/out directory is clear, the queued messages are in var/spool/mqueue.
We use Sendmail as our MTA , I'll ping our Unix admin on the setting that you
referenced below:
Since Mailman's out queue is clear, the issue is with Sendmail's
delivery of mail to the end user's MXs. There's not much Mailman can do
about this.
Mailman does have settings that affect how the mail is delivered to
Sendmail. For example, if VERP_DELIVERY_INTERVAL is set to 1, Mailman
will sent a separate message to Sendmail for each recipient, and
sentmail will in turn send separate messages to the recipient's MXs.
On the other hand, if VERP_DELIVERY_INTERVAL is set to 0, Mailman will
deliver messages to Sendmail in chunks with multiple recipients per
message. This in turn may allow Sendmail to deliver messages to
recipient MXs with multiple recipients instead of a separate message per
recipient which may improve Sendmail's delivery for these messages. This
depends on Sendmail's behavior when it receives a message with multiple
recipients in the same domain, and I don't know what that is or if it is
configurable.
