however some are normal gmail accounts (eg, Majority of others are Google Apps domain mail server accounts (eg, send SMTP lookup failure occurs with any of the gmail-based accounts - ie, does not appear to be specific to a Google Apps account or a normal gmail account haven't encountered problem with Yahoo but I don't use those accounts as frequently. Thunderbird manages over 20 email accounts which probably was 3.1.5 or whatever was previous since I usually do the upgrades) but I don't recall it occurring in my previous TB install. Thunderbird release v3.1.7 (happens very very very frequently) Obviously, connecting and sending the mail message is desired. Thunderbird dialog appears of 'Looking up. Close and restart Thunderbird (including closing any open compose messages) Copy message content to clipboard (and or a text file) I'm not worried this is some kind of hack or virus or malware since I recognize the address - it's the mail server I used well over ten years ago (in Thunderbird).User Agent: Mozilla/5.0 (Windows NT 6.1 WOW64 rv:9.0.1) Gecko/20100101 Firefox/9.0.1Ĭomposed mail message - Subject: Test Message: Test Even if I change the server address to something else (the IP address for instance), the pop-up still displays as location. If I look under Thunderbird's 'Server Settings', I see the correct address. What's even stranger is that the location (:995) isn't the address of my mail server. Oddly enough, If I go to Thunderbird's Certificate Manager, I see the certificate was actually added. If I click 'Get Messages' again, the pop-up reappears. If I click 'Confirm Security Exception', the popup disappears but no mail is retrieved. It is new however the pop-up appears while nothing has changed (other than Thunderbird updating). So every time I update the certificate, I get this popup. This pop-up isn't new to me since I'm using my own mail server with a self-signed certificate. I can't remember if it started immediately after the update so I'm not sure if the update was the direct cause.Īnyway, every time I try to retrieve my mail (by clicking 'Get Messages') a pop-up appears: A few days ago, Thunderbird updated to version 78.5.0.

I've been using Thunderbird for ages without any (real) problems.
