bug#11444: 23.3; smtpmail / lotus server

[Jason L. Wright]

Using smtpmail to send mail: M-x compose-email ... type type type,
^C^C, and the result back from the SMTP server is "500 Syntax error" when
using smtpmail talking to a Lotus (boo hiss!) server.  SMTP trace is
below.  I watched it with tcpdump and smtpmail is -not- doing anything
wrong (RFC-wise).  But the stupid server gets bent out of shape if the
\r\n's for the DATA command are sent in different packets.

Changing smtpmail-send-command from:

(defun smtpmail-send-command (process command)
  (goto-char (point-max))
  (if (string-match "\\`AUTH [A-Z]+ " command)
      (insert (match-string 0 command) "<omitted>\r\n")
    (insert command "\r\n"))
  (setq smtpmail-read-point (point))
  (process-send-string process command)
  (process-send-string process "\r\n"))

To (note the concat in process-send-string):
(defun smtpmail-send-command (process command)
  (goto-char (point-max))
  (if (string-match "\\`AUTH [A-Z]+ " command)
      (insert (match-string 0 command) "<omitted>\r\n")
    (insert command "\r\n"))
  (setq smtpmail-read-point (point))
  (process-send-string process (concat command "\r\n")))

This appears to fix it right up.  This isn't a bug with smtpmail, it's a
server bug (which I can't fix), but at least I can make the client
appease the server.

Amusing bug.  :-)

I've applied your fix to the Emacs 24 branch.  While not strictly
speaking a regression (since smtpmail.el has always done this),
smtpmail.el is going to get a lot more usage with Emacs 24.1, so I think
this minor change is warranted.
