I'm not sure if I understand your question "Who is your mail provider?"

Who owns the outgoing server? AT&T? Road Runner? Your work? The owner of
the server is your mail service provider. What's the server's name, if it's a
public server? If it's a server provided by your work, it's no wonder you
can't connect to it. It's unlikely a private business is going to make an
SMTP server available on the Internet.
