I would guess that they looked at what they were getting from a mis-configured
4.2 system when they designed their SMTP, and decided that that was right,

to use CR LF. This is essentially undocumented, and many amateur surgeons
pruned the wrong mailer definition when adapting a distributed file, or
left it out of a homebrew file. Our first parser only accepted CR LF,
and we got burned by having numerous support calls, each requiring that
we walk the customer through changing his sendmail.cf. In the next release,
we accepted either form. Berkeley has accepted either form since 4.2, but
the requirement for the extra argument makes me think that they started out
