Re: [Dovecot] dovecot-sieve with FreeBSD

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.
printf 'Subject: test1\n\ntesting!\n' | sendmail rgl@two.example.com
printf 'Subject: reject\n\ntesting!\n' | sendmail rgl@two.example.com
printf 'Subject: discard\n\ntesting!\n' | sendmail rgl@two.example.com
printf 'Subject: redirect\n\ntesting!\n' 

| sendmail -f alice@two.example.com rgl@two.example.com
printf 'Subject: redirect to bob\n\ntesting!\n' 

| sendmail -f alice@two.example.com rgl@two.example.com
printf 'Subject: test2\nX-Spam-Status: Yes\n\ntesting!\n' 

| sendmail rgl@two.example.com
printf 'Subject: vacation\n\ntesting!\n' 

| sendmail -f alice@two.example.com rgl@two.example.com
