386i sendmail problems

[John A. Shriver]

There SHOULD be a ^M at the end of every line in the SMTP data stream.
The sysV host is hosed.  SMTP (RFC 821) clearly defines that every line of
the SMTP transaction protocol ends with a <CRLF> (^M^J, \r\n).  (While RFC
821 never absolutely says that the text lines after the DATA command end
with <CRLF>, to interpret it any other way would be perverse.)  This is
consistent with the NVT model in the Telnet (RFC 854) protocol.

The UNIX-centric failure to put <CRLF> where <CRLF> belongs was a
consistent problem with the 4.2bsd networking code, one that was preserved
by many vendors when porting it their systems.  This probably happend on
your sysV system.

If the sysV machine uses sendmail, there may be some adjustments that can
be made to the M command line in the sendmail.cf file.  The E= argument
for any SMTP mailer should be E=\r\n, to tell the mailer to use <CRLF>.

You may also want to look at other sendmail.cf files, and make sure all
your machines are SMTP conformant.
