This appears to be because your server is responding in a non-standard
way.  The "-1" arises because an improperly formed SMTP response line
was received.

Try connecting using telnet ("telnet localhost 25") and see what you
get.  It should look something like the first line here:

    220 some.host.name blah blah blah

The first three characters are the critical part.  If they aren't
a three-digit SMTP response code, your server is likely borken.
If you post the results, someone might have some advice, but it's
not likely this is a Python issue.
