This usually happens when Mutt is misconfigured to use smtps for port 
587.  Your email shows it configured correctly, but you still may want 
to double check the value inside Mutt via ':set ?smtp_url'.

If that doesn't help, you might try running at debug level 2 (-d 2) or 
above and see if anything jumps out; it outputs to ~/.muttdebug0.  I 
believe Mutt would give a different error if there was a problem with 
the initial exchange or with the STARTTLS command, but maybe that would 
give some idea.

Finally, perhaps try connecting to port 587 via telnet and stepping 
through the EHLO and STARTTLS sequence yourself.  Perhaps the server is 
misconfigured and is giving an error message when trying to negotiate 
tls.
