Send one message to yourself. Does it appear in Sent Items? Does it
show on the Comcast Webmail site?

Yes, appears in the Sent box. Nope, doesn't show up at the Comcast
webmail site.

Check your settings.

Make the SMTP port 587 and make su My Server Requires
Authentication is checked.

All is as you suggest. SMTP is working fine, since all other mail,
even from other comcast senders, arrives fine. I can send from my
Comcast webmail to my OE, too, just not the other way around.
Nothing gets 'stuck' in the Draft or Out box.

This is really a mystery to me, as it worked earlier in the day.

How do I set up/configure Outlook Express, Windows Mail & Windows
Live Mail for Comcast email?

It is confusing the way you explain it. I would be talking to Comcast
techs, but they probably won't be able to help. They are among the
worst tech support out there.

Check into your anti-virus and make sure you are not scanning e-mail.

Turn off e-mail scanning in your anti-virus program. It is a
redundant layer of protection that eats up CPUs, slows down sending
and receiving, and causes a multitude of problems such as time-outs,
account setting changes and has even been responsible for loss of
messages. Your up-to-date A/V program will continue to protect you
sufficiently. For more, see:

Why you don't need your anti-virus to scan your email

Note that for some AV programs, it may be necessary to uninstall the
program and reinstall in Custom Mode and uncheck e-mail scanning when
the option arises.

The machine that is having the problem is my machine at work. Home
machines work fine. After doing more testing, I began to suspect not
the OE application, but my work's own network. When I got in this
morning, one email that I sent from my work address using my work
Outlook, received this cannot deliver after 16 hours:

"A copy of your message is being returned to you due to difficulties
encountered while attempting to deliver your mail.

The following errors occurred during message delivery processing:

smtp comcast.net 65534: expired after 16 hours,
problem was: 421 imta20.westchester.pa.mail.comcast.net comcast
Reverse DNS failure
: Try again later"

I checked with my IT department, and they are aware of the problem
(only with Comcast).

If only I got a similar 'cannot deliver' message when I sent out mail
from my Comcast address using OE...

Rvs DNS fixed. Back in business.
