IMAP messages not being retrieved on time from Comcast or Gmail
I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

Thunderbird uses limed message fatching and in the case of some servers like google utilizes push notifications as well.
Push notifications have sever limitations on the number of folders they work with and can only be sort of relied on for mail in the inbox.
Times mail fetch will occur in the time frame in your account settings. But not all mail folders are polled for mail. Specifically the trash/deleted and junk/spam folders are not polled for new mail unless you select them. ( right clicking the folder and selection properties allows for a folder to be included in the fetch if it is not.) Having said that various things can see a folder deselected, so check they are included in the folders to be polled for new mail.
I have seen new mail slowed or dropped if it is subject to mail scanners from antivirus programs. So I personally do not recommend email scanning, nor do I use it myself.
I'm only talking about new messages in the INBOX. I tried what you suggested anyways: 1. I disabled scanning of email and browser activity. 2. I added all non-INBOX folders to the scan.
No change. Just this morning (June 20, 11:00AM), I have received at least 15 email messages dated and timestamped yesterday (June 19, before 1:00PM).
To reiterate, I never had this problem on any PC with the same email accounts and the same network settings. Until Thunderbird upgraded to the latest version, I had ZERO problems on this PC. To blame any other source for the problem is just unfathomable. The only change is the version of Thunderbird, therefore, the only possible source of the problem is, you guessed it - Thunderbird.
Where can I file an actual bug report for this problem?
