vpopmail and postfix

As announced earlier, we tried to use vpopmail as postfix backend. 

There is a easy working 2 step solution. 

First you have to enter the following line in the postfix master.cf: 

vdelivermail unix - n n - - pipe 

flags=R user=qmailq argv=/var/qmail/bin/sendmail ${recipient} 

(Pay attention to use the path to qmail's sendmail!) 

Second edit the main.cf and enter: 

fallback_transport = vdelivermail 

Don't forget a "postfix reload"! This way you can still use postfix and /etc/password as "fallback_transport" is only valid for accounts that could be not handled by postfix. 

I guest this solution is a little bit oversized since it should be possible to call qmail-local instead of the sendmail emulation, but therefor it becomes neccessary to write a wrapper to map the interaction.
