Called Sitestar support. Messed around a lot in Thunderbird but I
think the
following did it:

Changed password
Changed username from kb****** to
Changed SMPT port from 25 to 587.

Now it sends messages. Haven't checked recieve because Thunderbird is
DLing
a ton of unread messages from the past month or so. Checked again -
receive
works too!

I'm guessing it was the username one. Some companies use just a
username, some a full email address, as the username. Especially (the
latter) if the company has taken over other companies, or at least their
customers' email handling.

I had that happen here. The ISP decided it would be cool to change
the domain name for the account, in such a way it broke my
email client. But I got lucky. Someone hand-edited my email
client and put support for that format in the code :-)
Worked a treat. They'd made that change to the program
(a program no longer supported), maybe five years before
I needed the capability. And that's what I call lucky.
