upgrade sarge2etch: sendmail doesn't work correctly

[Micha Borrmann <micha@borrmann.info>]

Hello,

yesterday I've updated a sarge system to etch.

I've one problem with sendmail. I'm using a certificate based  
relaying. The clients are verified from the system, but the SMTP  
connection are not used to sent mail.

In /var/log/mail.info the following lines are logged:

Apr 12 12:47:50 etch sm-mta[13211]: STARTTLS=server, relay=client  
[10.1.1.1], version=TLSv1/SSLv3, verify=OK, cipher=DHE-RSA-AES256-SHA,  
bits=256/256
Apr 12 12:47:50 etch sm-mta[13211]: l3CAlnL8013211: AUTH decode64  
error [1 for "="]

It's an up-to-date etch but with a sarge kernel  
(kernel-image-2.6.8-2-686), because a reboot of the system is not a  
good option.

Thanks for helpful hints

Micha
