OT: Comcast email is driving me crazy!!!

[chomiak7737 at att.net]

Hi all.

I got my friend set up with Comcast cable; the only snag was that after
the technician left attempts to use the internet solicited "forbidden" and
I had to call and get them to actually activate the modem which they of
course did very easily remotely. But the email is driving me crazy!!! I'm
having no problem setting up fetchmail for her to receive email but I
can't seem to get sending email right for her. Happen to be using postfix
but would be perfectly happy to use ssmtp or whatever other package for
which somebody can give me configuration tips. I keep getting an error
about:
host or domain name not found. Name service error for
name=smtp.comcast.net. type =A: host not found; try again. but when I
googled it seemed to indicate that the servers are mail.comcast.net for
retrieving--which is working and smtp.comcast.net for sending--which is
not working. When I tried telneting I say smtp.g.comcast.net but
trying this got me the same results as above--grrrrrrr!!!
Also, do I need
to use port 465 or not?

Tia.
