gmail via IMAP will no longer send or receive normally as of yesterday. No changes on my end.

Receive attempts - nothing happens Send attempts. This message: Sending of the message failed. Peer’s Certificate issuer is not recognized. The configuration related to smtp.gmail.com must be corrected.

The sent mail does not show in sent mailbox, but it does go through.

Thunderbird is in my list of 3rd party apps allowed access in Google account.

What Anti-Virus are you using ? Are you using Avast ? If yes: Disable the mail shield and restart Thunderbird to see if now works ok. Please report on results.

I'm using Norton. I tried disabling the firewall which did nothing but on your advice I turned off email protection and that seems to have done it...
