Thunderbird 78.5.0. Since the latest update of Thunderbird I cannot receive emails, both POP3 and IMAP. When I change the setting to 'transmit the password insecurely then it works. But I don't want to run my accounts that way obviously. Not entirely sure what to do. It appears to have something to do with security. I didn't change any settings when it just stopped working. Thanks for your help.

If you are using ESET/NOD32 security/AV then probability is very high it is causing your problems. According to ESET forums, you should temporarily disable SSL on ESET until they solve the problem per https://support.eset.com/en/kb3126-disable-ssl-filtering-in-eset-windows-products?ref=esf - the problem is being reported by dozens of users https://forum.eset.com/topic/26517-problems-with-thunderbird-and-imaps/ https://forum.eset.com/discover/

You might also inform them of your difficulty.

OMG Bingo! Exactly what I am using. I will contact them. Many thanks. Not sure about ESET anymore, although it has been quite secure. Can you recommend anything better than ESET?
