Thank you for your reply, Claus.
That's for SMTP -- if mutt is talking to an MTA (or MSA) it must use CRLF (though some MSAs fix bogus input instead of rejecting it).
Okay, so when Mutt is talking to the MTA/MSA through SMTP it's Mutt's responsibility to translate it. Mutt is already doing that in its built-in SMTP client so we're fine on that point.
If the mail submission is done via command line, then on Unix it's usually just LF, and the MSP handles the conversion.
I suspect this is the contention point for opensmtpd. When invoking $sendmail directly the headers and delimeter are all just LF. Is this expectation that the MSP perform conversion documented anywhere?
