Brad has given lots of good advice already in this thread including a
reference to
I want to emphasise that, as the thread seems to be concentrating more
on NFS.

In particular, look at Mailman's 'smtp' log and correlate that with
your MTA logs. Normally, you will see in your MTA log that a post has
been delivered to Mailman at some time and then you will see an entry
Mailman's 'smtp' log  x seconds later which says "<message-id>
smtp for n recips, completed in y seconds". Normally x is only slightly
larger (less than 2 seconds) than y. y is the time for all the SMTP
transactions to deliver the mail to the n list recipients, and y-x is
the sum of the times the message was queued in Mailman's in and out
queues and Mailman's non-SMTP processing time.

Also, are the 'missing' posts in the list's archive? Do the delayed
posts appear in the archive without delay?
