I'm a relative novice at this level of detail, can someone provide some
user-friendly pointers and/or instructions?

When I asked, I originally had in mind something like an interactive
command-line session where one could send a line, get a response, and so on.
Is this possible? If so, what would a basic set of commands be for, say, a
one-line body test message?

Yes, all messages fail when being sent to my ISP using exim. Is there a way
to test SMTP with another external site/server? I assume that since local
mail is being processed, the basic exim config is fine.

The puzzling thing is that the header is received and passed on by the
remote host, so the connection is established OK (refer back to the debug
output from my first post), it just seems to fail with the sending of the
body of the message.
