No, the RFC (2821) only affects SMTP.  It doesn't say anything about how a
commandline mail injection tool like /usr/sbin/sendmail should work.  Perhaps
the "real" sendmail just munges what you inject; qmail-inject doesn't  doesn't
do this.  Are your PHP scripts calling the qmail sendmail wrapper, or
qmail-inject?
