The extended error code (for example "5.1.1") is specified in RFC 1893,
the (#...) was taken from qmail (I think qmail-smtpd sends something
like "550 Domain not listed in rcpthosts (#5.1.2)").
The google results are RFC 2034 (ENHANCEDSTATUSCODES). If you want
those together with the ENHANCEDSTATUSCODES EHLO keyword, you MUST send
ALL messages in this format.
