the dovecot-lda sieve has an intree copy of libsieve. no need to install the cyrus version.

Dear Rui Lopes,

Greet. I am looking for a sieve tutorial like this for a long time. And this is what I need :)

Thanks.

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

HTH, Rui Lopes
