Hello,
I've a test system with postfix (SMTP), dovecot (IMAP only) and covecot-LDA (MDA) under FreeBSD-6.1. Currently everything works fine. But I wasn't able to install dovecot-sieve from the CVS. Does anyone has a small documentation howto install dovecot-sieve on FreeBSD.
Here are my little notes I've wrote while installing and testing.  I'm
still testing though, so, if you (or anyone else ;) find anything wrong,
have questions, give feedback!
== Sieve plugin for dovecot LDA

libsieve comes from the cyrus imap server (mail/cyrus-imapd23)

Obtain the sieve plugin from CVS:
cvs -d :pserver:anonymous@dovecot.org:/home/cvs co dovecot-sieve
On FreeBSD change the autogen.sh file contents to:
# using automake19, autoconf259, and libtool15 ports.
aclocal19 -I /usr/local/share/aclocal
autoheader259
libtoolize --force
automake19 --add-missing
autoconf259
Then, run it:
./autogen.sh
Install this sieve plugin:
# NB: Before you continue, make sure you didn't clean the dovecot
#     port when you've build it, eg: built it using:
#
#       cd /usr/ports/mail/dovecot/ && make install
#
#     You can clean it after you've build the sieve plugin though.
./configure 

--prefix=/usr/local 

--with-dovecot=/usr/ports/mail/dovecot/work/dovecot-1.0.rc7
make install
Configure dovecot to use the sieve plugin:
vim /usr/local/etc/dovecot.conf
protocol lda {
...
mail_plugins = cmusieve # ... other plugins
...
}
Make a test sieve script:
cat <<"EOF" > /var/vmail/two.example.com/rgl/.dovecot.sieve
require ["fileinto", "reject", "vacation"];
# * A sieve script is UTF-8 encoded.
#
# * folders are automatically created by the "fileinto" action.
#
# * By default (when no :comparator argument is given) all string
#   comparations are case-insensitive (in the ASCII range;
#   :comparator "i;ascii-casemap").
#   See the "2.7.3.   Comparators" section at
#   http://www.ietf.org/internet-drafts/draft-ietf-sieve-3028bis-09.txt
#
# See sieve information at
#   http://www.ietf.org/html.charters/sieve-charter.html
# For "vacation" see
#   http://ietfreport.isoc.org/idref/draft-ietf-sieve-vacation/
# Moved SPAM marked messages to the Spam folder and stop processing.
if header "X-Spam-Flag" "YES" {
fileinto "Spam";
stop;
}
# Move all mailer-daemon@ into a subfolder
if header
:contains
["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"]
[
"mailer-daemon@two.example.com",
"mailer-daemon@example.com",
"mailer-daemon@turbina.example.com"
] {
fileinto "mailer-daemon";
stop;
}
# OR, using :matches:
if header
:matches
["To", "Cc", "Bcc", "Reply-To", "In-Reply-To"]
["mailer-daemon@*"] {
fileinto "mailer-daemon";
stop;
}
# move all mail @foxie.example.com to a subfolder.
if header :matches "To" "*@foxie.example.com" {
fileinto "foxie";
stop;
}
# Some misc. tests follow.
if header :contains "subject" ["test1", "test3"] {
fileinto "test-odd";
} elsif header :contains "subject" ["test2", "test4"] {
fileinto "test-even";
} elsif header "subject" "reject" {
reject "reject test!";
} elsif header "subject" "discard" {
# discarded message are silently droped.
discard;
} elsif header "subject" "redirect" {
# this will redirect the message to "root" user, without storing the
# message in our mailbox.
# NB: Because, in my case, the "postmaster" is an alias to this same
#     mailbox, so we also test the loop prevention mechanism of
#     dovecot LDA.
#     AND in this case we will NOT receive any message on our email
#     box.
#     sent emails ids are stored inside ~/.dovecot.lda-dupes
redirect "postmaster@two.example.com";
} elsif header "subject" "redirect to bob" {
redirect "bob@two.example.com";
} elsif header "subject" "vacation" {
# sent emails ids are stored inside ~/.dovecot.lda-dupes in order to
# detect loops.
# List of auto replied senders are also stored here in order to
# prevent multiple replies to the same sender for a given period of
# time (defaults to 7 days [see src/libsieve/sieve.y];  min is 1 day,
# max is 31 days)
vacation "I'm out!  I'll reply when I get back";
}
EOF
NB: Errors on the sieve script are reported on the maillog and in a
file named .dovecot.sieve.err near the normal .dovecot.sieve.
# In this little "tests", I have several test mailboxes, like
# rgl@two.example.com, alice@two.example.com, etc, which are handled by
# dovecot LDA with a sieve script.
