dovecot-postfix

[Egbert Jan van den Bussche]

Since I had a problem after the last update, my main.cf was overwritten, 
I wonder if it is possible to uninstall just the combined 
dovecot-postfix package without doing harm to dovecot and postfix.

For some reason (somebody else installed trhe server) the ubuntu 
specific dovecot-postfix stack was installed but I always handled the 
server as separate postfix and dovecot server.

I would be very happy if I could get rid of JUST the dovecot-postfix 
stack. (and keep my main.cf from being overwritten in the future).

TIA
