Is there general agreement then, that this is a Sendmail problem and has
nothing to do with Majordomo?  In other words,  if I moved my list to
another Majordomo host that I'd be unlikely to have to contend with this?

I don't know whether the standard Sun sendmail is being used or if this one
was compiled by the ISP I'm using...

Another point of data if it helps:  It takes between 60-90 minutes for a
new posting to the list to make it out to subscribers.  I don't know if
that's just how long it takes, or if this indicates serious problems with
the ISP's mail configuration, or if the Majordomo script that handles
posting, runs on an infrequent schedule and it just so happens that the few
times I checked posting response the message has been sitting in the hopper
waiting for next posting job to run.  >60 minutes does seem like a long
time for a list with fewer than 500 addresses, however.

Thanks,

Brian
