I guess, now with ISPConfig 3 being that close to a release, it does not make any more sense to use ISPConfig 2 for a new installation.
I am yet to dive in on our new dedicated server, but I really would like to know, why courier was the preferred choice for ISPConfig 3, instead of dovecot. Looks like dovecot is the way to go nowadays.
In posting #15
it seems to be easy, to subsitute courier with dovecot, but I don't quite understand the last part with the config file, and on the other hand it is said, that dovecot will be supported by ISPConfig 3 in a later version.
So has anybody successfully installed dovecot instead of courier with ISPConfig 3, and can someone please post detailed instructions?
