I see no encryption here. I think this is why it is telling you that
it "cannot use a secure authentication method". I wrote "You might
want to check out port 587 but I think you'll be disappointed"
just this morning. As I wrote there, you should try port 465.

Looking at msmtp.pdf I'm almost certain you need tls on, even though
it could work that out for itself by looking at the port number, 465.

Change this to 465.

I'm not sure why you have this line if the previous one has just told
it the password already. I would remove it.

The comment above doesn't agree with the next line. It doesn't
construct the envelope-from; you've set it with "from martin.m@suddenlink.net"

This line duplicates one higher up. I think you need on.

I assume you haven't tried typing in my example, then.
