I've telnetted exchange and typed in the command "ehlo localhost". The
answer was:

250-mail.enterprise.de Hello [82.83.60.124]
250-TURN
250-SIZE
250-ETRN
250-PIPELINING
250-DSN
250-ENHANCEDSTATUSCODES
250-8bitmime
250-BINARYMIME
250-CHUNKING
250-VRFY
250-X-EXPS GSSAPI NTLM LOGIN
250-X-EXPS=LOGIN
250-AUTH GSSAPI NTLM LOGIN
250-AUTH=LOGIN
250-X-LINK2STATE
250-XEXCH50
250 OK

When I type in "help", exchange answeres this:

214-This server supports the following commands:
214 HELO EHLO STARTTLS RCPT DATA RSET MAIL QUIT HELP AUTH TURN ETRN BDAT
VRFY

I've done some tests with Thunderbird (all with authentication enabled):

without encryption: relay works
with TLS: error message STARTTLS is not offered in conjunction with EHLO
with TLS, if available: relay works
with SSL, but port 25: service not available or connection refused
(tcpdump says, there were a few packages)

Apparently it works w/o encryption but not w/ encryption?

By the way: I don't like exchange very much. :-)


Ideas?
