Incoming mail server (POP3):  type in mail.comcast.net
Outgoing mail server (SMTP): type in smtp.comcast.net.

if you are *ON* comcast connection, standard port 25 is fine.  However, i just switched to FIOS and found out rather abruptly that they block port 25, but luckily the company i get my pop3 e-mail service from supports the alternate port 587 (for outgoing e-mail). 

Just FYI in case you run into the same situation.

Traitor!

yeah... i know. comcast was really good to me. But Fios had a deal i couldn't refuse.  And well, there is this:

(i should preface by saying i'm now spending less on fios than i was on comcast, while getting faster speeds, unlimited long distance, and an HD DVR, not counting the free installation and $250 worth of gift cards for signing up... hard offer to pass up)

nice!

It's funny, i'm actually having a difficult time finding a server on speedtest.net to max out my connection... more specifically the upload speed.  I used to always use Washington DC, but the upload speed there maxed out around 15MB/s.  I've found Philly to be the best.

If comcast offered higher upload speeds i'd be all on it but its tough to pass up Fios 20/20. I need more upload YO!
