When Hobbit sees that the connection is established to the smtp port,
it sends all of the data listed in the "send" section. Then it waits for
any data to be returned.

Since the smtp server at the other end speaks proper SMTP protocol,
it will send the traditional "220" greeting first. This is what Hobbit
picks up, and compares with the "expect" string. It doesn't matter that
there might be a "250 Accepted" further into the data - Hobbit might not
pick up that data at all, since it just grabs the first packet of data
sent by the server.

:-) It is slightly complex, I agree.

It would be nice if Hobbit could engage in real protocol with different
types of services, but that would require some major re-working of the
network test code. It's possible, but definitely not at the top of my
to-do list.
