Things looked like part of our problems were with some
old DNS entries (that are managed by the block our ISP).

As a workaround, I changed the nameserver entries to
three Public DNS servers, downed the GWIA, then restarted

I haven't sat and watched a normal start of the GWIA before
so I'm not sure if what I'm seeing is normal operation, or if
something isn't working right and I need to put things back.

I'm seeing hundreds of "FETCH 1:142 (FLAGS UID) . . . OK FETCH COMPLETED"
remarks running on the GWIA screen. I tried sending a couple
of test messages out, but they're both showing (in their properties)
as "Transfer Delayed".

Is this normal operation . . . and should kick in after a space of
time, or do I have a problem here?
