Solution Found: After hours of searching someone finally figured out the problem with Comcast not sending emails: disable signature on outgoing emails. Don’t know what is blocking it but this solved the problems. Tried so many different combinations of ports –finally ended up with 995 incoming, 465 outgoing with SSL enabled on both. Everything works.

I wonder if this was resolved> – A different port?

Well I’ve had the same issues that happened only suddenly – in the last month. Been using the 587 with little problem. First, I was able to receive but not send – I would send and think it went out fine – no error messages.. but no one was receiving my Comcast emails. Then this week, I cannot receive OR send… so WTF Comcast???

This one sounds to me like it’s not a Comcast issue, and your web host is requiring authentication – It’s a checkbox in the advanced settings of Outlook – “My outgoing server requires authentication” -

Mine is a little different- I can send but can’t RECEIVE anything. I use Outlook and Outlook Express and have the same problem, can’t receive. I have gone through all the suggestions above and changed all the ports as suggested. Anyone have any other ideas???

Hello,
I have similar issues; 553 sorry #5.7.1

This ONLY happens when I hit reply, or forward. Effectively this means I can forward nothing and must always reply by creating a new message. In every other case, the mail goes through.
Comcast is no help whatsoever. They are condescending. I have Outlook 2007, I have port POP3, incoming 110, outgoing is 587
I use cybersitter 10 but they know of no issues.

6-29-10 I just got new computer w Office 2010 preinstalled. I cannot send OR receive email via Outlook 2010 and Comcast. Settings are correct. Nothing shows up in Inbox, but I do have unread emails. It IS already set to POP3 995 and SMTP port 587. I get no error messages. I deleted both email accounts, rebooted, and added them back. Same result. D’ya hHave any other ideas, plz? Thx!

Ok, solved my own problem. De-installed that &^%$* Norton that Comcast is now giving out free, and now everything is working great!!!

Im using Outlook and comcast. I just got off the phone with Comcast, they told me I had spyware and that is how my port got changed. Told me to change to 587, didnt work – so they told me to call Microsoft. I came here, used the SMTP port 465, works great!

But, my POP is still 110, and it will not receive. Can I possibly change that to something else? or do I have something else wrong?
