and than an user returns after 2 weeks vacation and dovecot starts
sorting 10000 mails?

sounds stupid no?:)

you keep the things seperated. you just no longer use the postfix
local/virtual for delivery but dovecot's lda (/usr/lib/dovecot/deliver)

all the rest of the smpt handling, spam checking is still done before
your mail is passed to dovecot's lda. another nice side effect of using
"deliver" is the auto updates for the indeces. that speeds up mail

i have that here running all fine with:
- postfix 2.3
- dovecot + dovecot-sasl
- dovecot-lda + sieve plugin
- mysql for virtual users
- postfixadmin to configure virtual users.


           openSUSE - SUSE Linux is my linux
               openSUSE is good for you
