Looks like it, but it shouldn't do that.  It should accept or reject the
 <spamtest> address and then allow the RSET to reset the envelope.  If
that's consistent behaviour, and you want to run the rest of the tests,
you'll need to find out what they are (or devise equivalents) and do each
by hand.  Some of them have to be run from a non-local connection, so you
might need an accomplice.
http://www.sxlist.com/techref/inet/smtpsend.htm  has a sample transcript if
you want to try individual tests by hand.  BTW, there is one shortcoming of
the tests -- they check to see if the mail is rejected at the time of the
SMTP exchange; some people have argued that it's OK to accept the mail so
long as it's not delivered.  Personally, I prefer not to have some spammer
wasting my resources and I prefer the mail to be rejected at the earliest
possible point.
