Can send but not receive emails after Comcast website upgrade with email

more options

Today Comcast set up a major new email system. When they did, I suddenly could not receive email through Thunderbird.

Comcast is switching to imap, but I don't need or want that. They said those who wanted to stay with Pop3 could do so. All we had to do for incoming mail was change the port to 995 and switch the incoming server from pop.comcast.net to mail.comcast.net. That's it.

However, while I can still send email, I cannot get it in Thunderbird (my new mail is successfully on the Comcast website). When I tell T-bird to "get mail" or when I open it up after being closed, it successfully connects with Comcast. It then successfully logs me in. Then it checks for new email. It takes much longer than usual. Then it says "No new email to download." But there is ... and a lot of it.

Comcast says it must be an issue with T-bird, I've double, tripled, quadrupled, and more -checked the settings. I've restarted my PC twice. I've rebooted the modem and router twice. Still no help.

Can anyone help? I'm beyond frustrated.

Chosen solution

Well ... at 11:45PM last night, over 22,000 emails began to flood my inbox. Comcast apparently marked every single email on the server as new with their new email program, so Thunderbird got 'em all. Ugh ... BUT ... at least the server and T-bird shook hands finally and came to a meeting of the tech.

It took 2 1/2 hrs for these emails to load and there was no way I could cancel it. I tried and nothing worked. Oh well.

Crisis over, thankfully ... for now, anyway!

Their forum is filled with the same complaint so not a Thunderbird issue. https://forums.xfinity.com/t5/Email-Web-Browsing/Change-in-POP3-port-from-110-to-995/td-p/3125461

Go to the Thunderbird Help menu and select Troubleshooting Information. Click Copy to Clipboard. Paste that in a reply window here on the forum.

Here you go. I am using an old T-bird version, but I'm happy with it and I've had no problems. I got plenty of email this morning before the problems began.

Your incoming settings look correct but your SMTP should have SSL . Check your firewall to see if it is blocking Thunderbird. https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email

Nope, not being blocked; doesn't show anywhere. Like I said, it worked fine today, right up until the change happened. I can send; just nothing incoming will come through. It keeps saying there are no messages to download.

Did you look at the xfinity forum I linked to? They are discussing the change there. Not really much of a change. I have been using port 995 with SSL for a year or better. I actually have my Comcast account setup as both IMAP and POP in Thunderbird so I can test things.

Yes, I did look. Lots of posts and not easy to follow there are so many. The thread goes back to 2016 so it's really hard to find details of the most recent event. Maybe it's spread out, but the topics I looked at didn't help me much.

I actually have been using port 995 for several years. All I had to change today was the incoming server, from pop to mail. Still no mail. I'm at a loss and very frustrated.

Well so much for it being a Thunderbird issue per the Comcast helpless desk. :) Glad your back working. 22,000 emails? It might be time to clean up your Inbox on the server.
