msmtp TLS timeout - gmail-imap

Question

I've looked through the list of possible solutions, but I don't see this problem, here it is.
I had been using smtp for years for my crontab entry to provide status updates via email. Then it quit this week, and I was unable to fix it. Then I saw that it had become orphaned, and the suggestion was to move to msmtp. So I downloaded and installed it on my Ubuntu 18.10 system.
I'm trying to send email to my myaccount#gmail.com account.
It appears that I'm communicating properly with the gmail smtp server, as the debug below show. But it always gets a TLS Timeout.
I also don't understand why I have multiple EHLO entries. My system does not have a DNS domain name, so that I'm not sure what to put here; localhost seems to be working OK. Also, my Thunderbird emailer is working correctly with gmail.
Here's the debug output:
echo "Hello there" | msmtp --debug myaccount#gmail.com >/tmp/msmtpOut.txt
ignoring system configuration file /etc/msmtprc: No such file or directory
loaded user configuration file /home/myhome/.msmtprc

Answer 1

Build msmtp using --with-tls=openssl to solve the problem.
As regards as the EHLO command sent twice the RFC3207 states:
The server MUST discard any knowledge
obtained from the client, such as the argument to the EHLO command,
which was not obtained from the TLS negotiation itself. The client
MUST discard any knowledge obtained from the server, such as the list
of SMTP service extensions, which was not obtained from the TLS
negotiation itself. The client SHOULD send an EHLO command as the
first command after a successful TLS negotiation.
So that is the normal behaviour.
