If you were a mutt user, I would ask what msmtp buys you that mutt
can't do by itself. But I believe you're not, so this might well be a
good choice for you.

Local delivery would be working already if you were using smarthost
rather than satellite in the first place. smarthost has the benefit
that you can retry exim any time you feel like it in future.
(I'm assuming you'll point your preferred MUA (mail client) at msmtp.)

If .mailrc is something to do with your MUA, then that's probably the
file to point at msmtp with. I don't have the documentation.

You might want to check out port 587 but I think you'll be disappointed.
But, you can still play with a hand-crafted email to test your
authentication on an encrypted port just by replacing one line.
Where it said:
$ openssl s_client -starttls smtp -crlf -connect smtp.suddenlink.net:587
substitute:
$ openssl s_client -connect smtp.suddenlink.net:465
The gobbledegook will be slightly different, ending up something like
...
Start Time: 1437146188
Timeout : 300 (sec)
Verify return code: 20 (unable to get local issuer certificate)
---
220 ....suddenlink.net ESMTP server ... ready ...
and typing:
ehlo something
will tell you, amongst the code 250 lines that you can use plain
authentication as in the example I posted before. So it looks like
that's the port (465) for you to use.
You won't want to set "tls_starttls on" obviously, but you may or may
not need to set "tls on" because port 465 can't work without it; it
pops up spouting gobbledegook already.
Cheers,
David.
