This is my set-up at home also (except that my home LAN is all Mac 8^] ),
and I get my mail from my SIMS server at work.

So you have them using POP-before-send for authentication? That's as
opposed to SMTP AUTH as in your message subject -- they're two different
methods.

If you're using POP-before-send, OE (or any mail client) will authenticate
only when it logs into a POP session to check mail. It will not
authenticate any SMTP session when it sends mail.

If I understand you correctly, it's not necessarily the Airport timing out
and disconnecting that's causing SIMS to expire the client's authentication
(although acquiring a new IP address would certainly do that), it's that
they haven't checked their mail via POP for longer than five minutes (your
configured time-out for SIMS' POP-before-send), so SIMS times out their
authentication window and they have to POP their mail again to renew their
authentication. It's not good enough to just check your mail once and then
expect to be able to send mail for the rest of your session. You have to
have checked mail (i.e. logged into SIMS' POP server) no more than five
minutes prior to sending mail.

This is the problem with POP-before-send -- the user has to either remember
to check mail before sending, or set his/her mail client to automatically
check mail at least as often as SIMS authentication window. All around,
it's a PITA. It's better to use SMTP AUTH, if the mail client supports it,
so that the mail client authenticates SMTP (sending) connections with
username/password. That's what I do (using Mailsmith) from my home Airport
network and it works flawlessly. If you have your client use SMTP AUTH, you
should enable the 'Advertise SMTP AUTH' checkbox in SIMS' SMTP settings.
IIRC, some mail clients won't attempt to use it if the server doesn't say
that it supports it.
If your client can't or won't use SMTP AUTH, you might want to try
increasing SIMS' POP-before-send time-out and/or have the client increase
their Airport's idle time-out (five minutes seems a bit short to me for the
Airport time-out anyway).
