This is more along the lines of a support request.
Does your issue sound like any of these https://mzl.la/39KrVSi ?

Actually this sounds like the hundreds, or is it thousands of support topics over the years where anti virus products can't do their job and terminated the download because you have received a malformed email. Generally the mail scanner crashes and the connection eventually times out. One to start again on the next mail fetch.

Sometimes, clearing the spam folder in web mail is enough. Other times you have to disable mail scanning in the anti virus product until the email that it can't cope with actually downloads.

Bug 1762327 fixed it for Thunderbird 102. I don't we'd be modifying 91 at this point.

NO Magnus, you have limited the number to download to 20. You have not fixed it. The root issue is antivirus products that choke and die on malformed emails. The result is the connection then times out and the mail which has been downloaded is downloaded again in the next session. As the vast majority of these are with folk that have significantly less that 20 email in the queue the fix in Bug 1762327 will do nothing for this. What is needed is some form of recovery from a session timeout where mail has been downloaded, like perhaps write them to the popstate.dat file if the session times out.

That would however make identifying these cases more difficult, as the user will then see mail simply not coming in without the identifying last few repeating which we use in support to identify these cases.

Please comment if you still see this when using version 102 with Windows started in safe mode.
