Thanks a lot for the sarcastic google hint (even I had to smile) - but 
I'm not living behind the moon plus I wouldn't bother asking if I would 
find hints somwhere else ;)
Dovecot's SSL/TLS capability is configured as told by: 
http://wiki.dovecot.org/SSL/CertificateCreation PLUS it uses to run 
without any issues on other MTAs.
There is something else missed - I just don't get it ;/

Best Regards
