First, thanks for the info so far... It is rather problematic attempting to trouble-shoot a Mac that is 3,000 miles away!

SMTP port 587 is almost Universal
That hasn't been my experience; the times that I have used an alternative port for sending e-mail it has always been a unique number and it wasn't 587. For example, the alternative port for my hosting company is 2525, and I understand that is a common alternative port...

I get the distinct impression that Comcast absolutely, positively wants any and every user to use their outbound servers
That may be true, but it is common for folks to use alternative e-mail servers for a variety of reasons. At any rate, my friend's e-mail problem is separate from her issues with Verizon (she was just curious about Comcast as an option to Verizon's seemingly poor tech support.) She just wants to be able to send e-mail via her Web host's servers. And she wants to be able to send e-mail when she is away from home and SMTP port 25 is blocked, which is very common when trying to send e-mail when on a network that isn't "yours."
For that matter, when I use Witopia's personalVPN I bypass Charter's servers altogether, so Charter doesn't even know that I am online and my usage isn't logged by Charter.
My friend mentioned that Verizon left a CD with her; she didn't mention anything about a booklet with set-up instructions. So I will give her a call and see if she has the instructions.
She has been using an Airport base station to wireless connect to her printer; I assume that it isn't an option if she uses Verizon's router...
I think that she will probably have to find someone locally that does Mac tech support in order to get this all sorted out...
Hey Chris... Did you get the PM I sent you a day or two ago???
Due to a temporary work stoppage, you may experience longer than normal hold times when calling our customer service centers. We apologize for the inconvenience and appreciate your patience.
It's also the weekend which is always a bad time.

But there is another SMTP submission port, port 587, which almost all mail server supports. In fact, according to the relevant standard, port 587 is the preferred port for mail submission. But even if the mail server software supports it, it may or may not be turned on. You need to check with the administrator or hosting service. Not all large hosting services support port 587.

Gmail uses 587 for POP and 465 for IMAP

The Internet Engineering Task Force (IETF)
3.1. Submission Identification
Port 587 is reserved for email message submission as specified in
this document. Messages received on this port are defined to be
submissions. The protocol used is ESMTP [SMTP-MTA, ESMTP], with
additional restrictions as specified here.
While most email clients and servers can be configured to use port
587 instead of 25, there are cases where this is not possible or
convenient. A site MAY choose to use port 25 for message submission,
by designating some hosts to be MSAs and others to be MTAs.

These are just a few examples, she could try port 26 which is what this server uses.
