I'm having trouble sending emails from my gmail accounts. It gets stuck on "Connecting to smtp.gmail.com...", after a few seconds an error message appears: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

I've confirmed that the settings are being used correctly https://prod-cdn.sumo.mozilla.net/uploads/images/2018-01-18-12-43-59-44a50f.png

And on the smtp settings https://prod-cdn.sumo.mozilla.net/uploads/images/2018-01-18-12-44-02-3ead30.png (username is my email) ... after Google's info: https://support.google.com/a/answer/176600?hl=en

The only thing I'm unsure of is authentication method. Thunderbird's default is 0Auth2, but while browsing the internet the preferred method seems to be Encrypted password. I have, of course, tried both - same problem.

Thunderbird version: 52.5.2 Windows 10 (x64) Incoming email works and SMTP works for another provider (yandex)

Turns out it was a firewall issue.

I'm using a VPN and solved it by adding a general rule to Iptables: iptables -A OUTPUT -p tcp --dport 465 -j ACCEPT (Google seems be picky or something)

I added the rule and it seems to work. Of course 1 email isn't conclusive. I do hope that this is it though. Thank you.
