Brian, thank you for getting into this problem.

By "properly authenticate to your own server", I presume you mean checking
"My outgoing server (SMTP) requires authentication" in the Outgoing Server
tab after clicking More Settings in Outlook 2003 account setup. If you mean
something else (or more), please explain. My email accounts have always been
set up with this option turned ON. Why might this not suffice (as you imply
it should)?

Also, can you tell me how to identify the ISP I'm connected to when I'm
travelling to various vacation spots? Here in Scottsdale, AZ, I am connected
to a non-secure condominium wi-fi network, but I can also connect hardwire to
a Cox cable modem. I have no problem receiving emails or getting Internet
access on either of these connections. But is there any generic way, online,
to identify a wi-fi ISP and get its outgoing port numbers and any other
required settings?

Thanks for any help help you can give me.

I am retired, and this notebook computer goes with us to various

"work ISP" at our varying destinations. Therefore, it seems that my
practical options are your suggestions 3a (which I will pursue), 3b
(which I'm now doing, clumsily), and 3c(1). I want nothing to do with
AOL.

If you are traveling with your PC and connect to different ISPs, then you
must either change your account to use the SMTP server of the ISP to which
you connect, or you must properly authenticate to your own server. Many
ISPs do not like to transmit messages on their networks that appear to come
from another network.
