This looks like you can manually choose the LOGIN authentication method
using "auth login" in your .msmtprc. That should work, but since you are
not using TLS, your password will be sent unencrypted over the net.

If you are using a secure VPN to connect to your company's network, that
might be acceptable. Otherwise, you could try to find out if the server
supports TLS on a different port, i.e. without STARTTLS:
msmtp --serverinfo --host=exchange --tls --tls-starttls=off --tls-certcheck=off

If this works, use "tls on", "tls_starttls off" and "tls_trustfile
/path/to/file" to use TLS.
