SMTP Configuration -- No Hostname

[ckiszka]

I'm not sure if this is an issue or not. When SMTP is configured, it is not sending the hostname and the SMTP server is rejecting on helo ("Helo command rejected: need fully-qualified hostname;..."). Im using the latest docker container and using the --hostname argument. If exec into the image, the hostname is correct.

In looking into the container logs it looks like the Sendmail is not sending the hostname? The /etc/hosts file and hostname are configured. I implemented a work around on the mail server by skipping the helo restriction if they have authenticated. Not really what I wanted to do but it works now.
