Alan, you can use sieve with dovecot in an offline imap setup.

All you have to do is compile sieve into dovecot:

wget http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.2.tar.gz

untar it

cd /usr/local/src/dovecot-2.2-pigeonhole-0.4.2/

./configure --prefix=/usr/local/Cellar/pigeonhole/0.4.0 --with-dovecot=/usr/local/opt/dovecot/lib/dovecot
make && make install

I did this on a Macbook with dovecot installed from hombrew.

Whenever imap process is launched by my mail client it automatically sorts my
INBOX based on sieve rules.

I can also do this manually:

sieve-filter -e -W -v -C -u $USER ~/Messages/dovecot.sieve 'INBOX'

Hope that is of some help.
