[HowTo] Replace courier with dovecot

[tera]

Hmmm, okay - I've got more problems and they are too much to resolve in the short time to have both servers online. The thing is that I migrate to a new system for deactivating the old one and this should happens within this day.
The old directories are within completely different formats (eg .Sent/cur/) and the migration-script from dovecot org doesn't resolve it to something like mail/Sent/
So I would have soo much to do - I will migrate firstly to the new server and realize dovecot at another time...

My way was to put through the update to 1.0.4 and now I have courier back and everything's fine again. Hope that I have the time to realize dovecot, roundcube, sieve and pwchanger soon
