It seems no STARTTLS nor authentication took place (and this is
probably why the server complains).  Are you sure the configuration is
correct?  Have you installed the external STARTTLS binary?  It is
required for STARTTLS.

If you frob `smtpmail-debug-info', how do the trace buffer look?  Is
STARTTLS activated? Are authentication used?  Do you know exactly what
the server requires, in terms of security level?

I don't know how to answer your last question.  This is what the trace
buffer looks like, after "pleased to meet you":

Mac OS X smtpmail "encryption too weak"

[Gilbert Harman]

I used to be able to use emacs to connect to the mail server at my
university, but recently the university smtp server has required
authentication and now I get the following error: "encryption too weak"

503 5.7.0 encryption too weak 0 less than 39
221 2.0.0 smtpserver2.Princeton.EDU closing connection
smtpmail-send-it: Sending failed; SMTP protocol error

I am using Mac OS 10.2.1 and emacs 21.3.50.1.  In addition to the rmail
stuff that used to work, my .emacs file includes:

(setq smtpmail-auth-credentials
      '(("smptauth.princeton.edu" 25 "myusername" "mypassword")))
(setq smtpmail-starttls-credentials
      '(("smptauth.princeton.edu" 25 "~/.my_smtp_tls.key"
         "~/.my_smtp_tls.cert")))

I have no trouble using the Mac Mail program to send and receive mail using
the new authentication.  But I can't seem to get mail working from within
emacs.
