Hi

  I recently started using wcSAP, and have noticed what I'd consider a
false negative (allowing potential spam).  In the log file clip below, the
"wcsap-openrelay-test-123sxa23@alqwejad.com" address is rejected because
the server only allows 1 RCPT per connection, not because it's trying to relay.

Perhaps after the 1st RCPT is sent and accepted a RSET command could be
issued before the 2nd one is tested.
