Re: Netsendmail inserts double line endings?

OK, I've confirmed that this is the case.  Although it is, of course,
correct to send CR LF in mail messages and the SMTP protocol, I'm not
sure that it's correct to send CR LF to /usr/sbin/sendmail.  Surely
the "protocol" being used between the process and /usr/sbin/sendmail
is pure Unix, therefore LF-terminated?

Exim doesn't mind about the CR LF in the mail headers.  In the body,
it gets confused, and appears to turn CR LF into LF LF.  By "body",
I'm also including the MIME headers for each of the two parts.

The *really* weird thing about this bug, however, is that it only
bites when sending mail non-locally.  I can send mail locally (through
exim), and it comes out just fine.  When I send it non-locally, we get
the bug.

Anyway, in the meantime I have been able to workaround the bug,
for both local and non-local mail, quite successfully, using:

Netsendmail.sendmail ~mailer:"tr -d '\\015' | /usr/sbin/sendmail" msg 

Attached is my test program.
