Sudden inability to receive email
A few days ago, I suddenly quit receiving emails to my Comcast account. After realizing this, I set up for the emails to also go to my Outlook account and am now receiving them there. I can compose and send from Comcast but not receive. Nothing I've tried has resolved the issue so far.

First, could you please log in to your Xfinity email account directly through the Xfinity Connect website (https://connect.xfinity.com/)? This will help us determine if the issue is specific to how you're accessing your email (like through a desktop client or mobile app) or if it's with the account itself.
Once you're logged in through the website, could you check a few things for me?
If you've checked these areas and still aren't seeing your missing emails, there are a few other things we can investigate on my end.

My comcast email accounts (all 3 of them) suddenly stopped being able to send email, a couple of days ago!
I initially was sending from my iPhone using the iOS mail app. I checked the server settings and even re-entered my password in both the POP and SMTP configuration settings. (Although nothing should have changed and sending was working the day before... not that I send many emails). I logged into my Xfinity email and was able to access it with the same username and password.
I then tried sending from my Mac using Mac Mail app and had the same issue. The Mail Connection Doctor app (available from the MacOS Mail app) shows that the SMTP server status is "red" for each of the 3 comcast accounts...while the POP and IMAP servers are fine. The detail description with the status says that the Mail app couldn't connect and to check the network (it's fine, I can receive email), check that I have the correct information in the Account preferences (it worked the day before and re-entering the same info was no help), and to verify the server supports SSL (comcast requires it).
I had this same problem a year or two ago. I attempted to work with Xfinity/Comcast but they were no help and continued to blame me. The ultimately recommended that I stop using 3rd party clients (ridiculous) and use their web app to handle my email. I spend may hours with Comcast that time. This time, I can't get past the chat bot / AI but it doesn't know what to do with email problems and I can't get a live agent. Ultimately, the problem was resolved by waiting. A couple of days later, the SMTP servers started working occasionally. I could send email, have it fail, leave it in my outbox, and at some point it would be sent. A few days after that, send email would work consistently. My interpretation of the problem is that Comcast has no idea how to maintain its SMTP mail servers and occasionally screws things up without realizing it and it takes a few days to get figure it out and get things working again. Crossing my fingers that this is fixed Monday morning (tomorrow).
Update:
Looking at the logs generated by the Mac Mail Connection Doctor app, I can see that the SMTP server fails due to it thinking that I've failed authentication excessively. I don't see how this can be true since I did nothing different from I've been doing for years. (This is the same error I was getting when I ran into the problem a couple of years ago.) Here's the full text of the relevant log entry:
READ Aug 17 13:43:38.528 [kCFStreamSocketSecurityLevelTLSv1_2] -- host:smtp.comcast.net -- port:465 -- socket:0x600006a6fe40 -- thread:0x6000057c7300

This morning, I can send an email just fine, but I am not getting my messages. What is going on? Any technical issues? I have had problems with my accounts over the years, but I never had this particular problem. I sent a message to my alternative email from my Comcast email, and I had absolutely no problem. Does anyone have any suggestions? My settings are fine.

Xfinity has no good technical support when this happens. On phone for 2 hours and he just kept telling me to change my password which did not help. He is reading a list of problems that don't answer mine. Went to the Xfinity store and those folks are not techs and so very limited. Waited there for 2 hours to get on some virtual assistant computer but the guy before me never finished his problem so I left. THIS IS WHAT I PAY FOR? Still no emails coming in but I can send them out to others but not myself.
Have a nice day!
