[Pkg-exim4-users] smth auth client with exchange server

[Wolfgang Kohnen]

Hello, folks!

I have to use a m$ exchange smarthost for my exim servers (sic!) and I
need exim to do smtp auth (as client) for this. /etc/exim4/passwd.client
lists the proper credentials. Because the DNS A record and PTR record
differ, I've copied the line and changed the server name on the copied
line to the PTR correspondent hostname. Both hostnames as DCsmarthost do
not work. This error message appears in mainlog:

2006-11-27 11:22:07 1GodcX-0003i2-RO ** test at web.de R=smarthost
T=remote_smtp_smarthost: SMTP error from remote mailer afte
r RCPT TO:<test at web.de>: host mail.enterprise.de [10.10.10.2]: 550 5.7.1
Unable to relay for test at web.de

Where mail.enterpise.de is my smarthost and test at web.de is a remote mail
address. A test with Thunderbird as client with the same credentials
work perfectly.  My guess is, that the TLS and AUTH handshakes do not
work properly. Do you have a clue how to get this working?

TIA!

ps: I've tried to set tls_tempfail_tryclear = true -- with the same result.
