For a while when sending Gmail emails via Thunderbird on a desktop (Windows 10) I've been getting messages about security exceptions relating to smtp.gmail.com:465. The grey box says the certificate isn't verified but I confirm the security exception and tick the box to store the exception permanently. The send usually then fails the first time, but when I click Send again it goes and is delivered. This has been going on for a while but is little bother and I figured whatever isn't right will catch up with itself eventually in updates.
Then - after a Thunderbird update a couple of days ago I couldn't get it to download Gmail emails at all. It was getting stuck at "connected to imap.....".
This morning I've spent a couple of hours trying to figure out what's going on. I have done a number of Google searches and picked up various sites with info on how things should be set up without finding anything wrong. Eventually I found that if I go into the Norton antivirus settings and turn off "scan inbound emails POP3 IMAP4" the "connected to imap....." problem goes away. Emails are now downloading for both Gmail accounts without any problem.
My question now is how much risk I have opened up by switching off that scan of incoming emails. We keep email set to display simple html and are pretty savvy about not clicking anything that might be dodgy. Is it safe to leave as is?
The security exception message when sending email is still happening though and I can't see any way to fix it. Is it something to worry about or just put up with until the certificate update is eventually done by Google (assuming that that is what is needed)?
