Sometimes I have to quote the appropriate RFC in order to convince someone
else, though. :) Thanks, your pages contained a pointer to RFC 1869,
which specifies 555:
If the server SMTP does not recognize or cannot implement one or more
of the parameters associated with a particular MAIL FROM or RCPT TO
command, it will return code 555.
I'll pass that back.
