Forwarding message filter times out sending email
I built a message filter to forward emails under certain conditions. When I run the filter on the emails, after a long while, I receive the following message:
Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out. Try again.
Yet, I can manually forward the email.
Thunderbird 68.4.1 (64-bit), Ubuntu 18.04.3.
