Cannot send messages from gmail account

I am finding Thunderbird more and more frustrating by the day. If it isn’t sending messages from inbox to trash, it is not working properly on some other front.
Anyway, the latest is that I can not send messages from the gmail account I have. I get the following message;
Sending of the message failed.
The message could not be sent because the connection to Outgoing server (SMTP) was lost in the middle of the transaction. Try again.

Any thoughts? I am able to send messages just fine using my phone and the gmail app, but no luck here.


Hey Todd, I think you mean to post this over in the Thunderbird forum : You may want to try over there. This is a forum about the Mozilla Identity and Access Management system.
