I'm far from being an expert on this, and have had my share of problems, all of which have been answered here with the help of those more able.
I too have comcast, and went through much the same thing when I replaced my modem and router. The best I can do is tell you what my settings are. I can't really give you an explanation of why. Be aware also that your settings are determined, to some extent, by the security settings you have set on your modem and router.
Go to Tools\Internet Options|Sending (SMTP)\Edit.
General: Enter a name for this definition: SMTP <default>
Server host name: smtp.comcast.net
Server TCP/IP port: 465
Timeout: 180
Security: Via direct SSL connect
SMTP Authorization: Login to the SMTP server...: Username: xxxx (whatever is to the left of the "@" in your email address).
Password: yyyy (as an example. Your password, of course, is of your own choosing)
Maybe that will help. The important part, I think, is to have the security setting match your modem and/or router.
