I guess I said that too early. With Google's help, I've made a  
successful connection to tmda-ofmipd using openssl. openssl writes a  
lot of certificate info that appears to be correct, and eventually I  
get the desired "220 servername ESMTP tmda-ofmipd" response.

Then after entering "AUTH PLAIN
AGptczFAam1zMS5uZXQAbm90Lm15LnJlYWwucGFzc3dvcmQ=" (a bogus hash, but
presumably that should just cause tmda-ofmipd to reject the
authentication rather than crashing), tmda-ofmipd crashes:

Just to make sure it had nothing to do with EHLO commands and such  
entered after the secure connection had started, I configured  
tmda-ofmipd to start with SSL rather than optional TLS. Connecting  
with an email client configured to use SSL, the ofmipd debug output is:

I don't know anything about Python or its exception traces, but it  
seems to me that something is wrong in some "asyncore.py" file?

Any suggestions?

Thanks,
