Just to make it clear, RFC2821 is likely being violated:
- The reserved mailbox name "postmaster" may be used in a RCPT
command without domain qualification (see section 4.1.1.3) and
MUST be accepted if so used.
This is *probably* being violated, but I'm not sure as it gets ambiguous
later.
However, returning a 550 is very wrong. The correct reply should be
either:
554 Transaction failed (Or, in the case of a connection-opening
response, "No SMTP service here")
or:
502 Command not implemented
