Hello: I am unsure of what your message means; did you intend "ubuntu <> thunderbird'?
Regardless, my question remains. As stated, my problem is not only evident with thunderbird, but shows up in at least 3 other email clients (Evolution, Geary, Claws Mail). This would indicate the problem is not with thunderbird, but with the SMTP processes. Any ideas on the cause of this behaviour would be greatly appreciated.

I did not see this problem with my previous ISP. In both plain text and HTML formats, if the body of the email is greater than approx. 930 characters, when I click <Send>, the progress window goes to 100% sent, then hangs and eventually times out with the message not being sent. It shows an error message: "Sending of message failed The message could not be sent using Outgoing server for an unknown reason. Pleas verify that your Outgoing server settings are correct and try again." I have contacted the new ISP about this and they have no idea what is causing this except it is not a problem with their SMTP host. All email settings are as directed by the new ISP. I have confirmed this on 2 computers, both running the same software by creating messages with known character counts of over 1000 characters, created in a basic text editor, and progressively deleting characters until it is successfully sent and recounting the characters. I do not see this problem on a Windows 10 machine using the same version of Thunderbird. I have also tried different email clients on Ubuntu and see the same issue. I am at a loss, so any possible clues as to what is going on would be greatly appreciated.
