im looking for a good howto to install kopano on my ubuntu / debain system.
Maybe the best option is when i can install kopano without a postfix.
I have a Email server, and i will fetch the emails about my own mail server.
-> Sending and received with mail1.server
-> Kopano = kopano1.server.de
Kopano on Ubuntu or debian
I successfully use Kopano from the community builds using sendmail for both receiving and sending emails if that helps.
