I'd like to tell you it is working but you are right about the
port. I tried your suggestion but turned off starttls this time
as starttls turned on causes a short hang followed by a message
stating that starttls won't work.
I freely admit I do not understand the fine details of
TLS other than it is a trust system based on certificates and
you get end-to-end encryption of the session. Here's how this
session went. I assume the text came encrypted with TLS. The
lines now have a carriage return after them. Since I piped all
output to a file, the standard error came in first.

I see what msmtp means about the password. I bet the
encoded string is the base64 password you mentioned.
Anyway, thanks! I think we are inching (more like millimetering)
forward.
