First step is to have a mail system that works without sieve. This is 
the hard part. Depending on your preferred distro here are two nice 
webpages for this:

http://workaround.org/ispmail

Second step is to enable sieve, for witch you only need to uncomment the 
specific lines from dovecot.conf. For dovecot 1.2, you will have 
something like:

protocols = pop3 pop3s imap imaps managesieve
protocol lda  {
   ...
   mail_plugins: quota sieve
}
protocol managesieve {
}
plugin {
   ...
     sieve=~/.dovecot.sieve
     sieve_dir=~/sieve
}
