msmtp Questions

["Martin G. McCormick" <martin@server1.shellworld.net>]

The fun never ends. I installed msmtp and as near as I can tell
it works as advertised.  My SMTP smarthost at
Suddenlink.net presents the following banner which nicely
explains what one needs to do to get real work done. I've had a
little trouble getting msmtp to fit what is required. The
documentation provided by Suddenlink says that smtp is provided
on ports 25 and 587 and both display the following banner:

SMTP server at smtp.suddenlink.net (smtp.suddenlink.net [208.180.40.68]), port 587:
    txasav-vm06.suddenlink.net ESMTP server (InterMail vM.8.04.03.20 201-2389-100-164-20150330) ready Fri, 17 Jul 2015 19:59:42 -0500

    AUTH:
        Supported authentication methods:

	Here's the .msmtprc file with password redacted.

# Set default values for all following accounts.
defaults
tls off
tls_trust_file /etc/ssl/certs/ca-certificates.crt
logfile ~/.msmtp.log

# Set a default account

# The SMTP smarthost.

user martin.m
password 'IfItoldu,Idhave2'
passwordeval eval

# Construct envelope-from addresses of the form "user@oursite.example".

# Don't use starttls.
tls off
tls_starttls off

# Syslog logging with facility LOG_MAIL instead of the default LOG_USER.
syslog LOG_MAIL


When I run a test by piping a file in to msmtp, I get

	Believe it or not, this is the closest I have gotten to
making anything work.
