Hello Tom,

You could simply enable sieve in the dovecot environment. The offlineimap + dovecot setup you have running already can be left mostly intact: it has nothing to do with offlineimap.

You could just setup sieve per the dovecot wiki guidelines, and then create a sieve script that uses the ext_programs plugin to call dspam (or any other filter that adds headers and is able to print the message including those added headers to stdout).

Thank you for the suggestion. This is indeed what I'm trying to do.

I'm not sure if it's necessary to do the delivery to dovecot using Dovecot's deliver LDA, or that you can keep using the '...libexec/dovecot/imap' binary for that in order to have sieve support. Maybe someone else can fill that in.

This is the crux of my question, I guess. Right now I don't deliver any mail, but use offlineimap to keep a local imap server (dovecot) in sync with a remote one. So my questions are:

1. Can I use dovecot's sieves if I don't deliver mail?
2. If not, how can I hook up offlineimap and dovecot so that mail is delivered instead of synchronized?

Thanks,

Alan

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....

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.

This is most helpful, thanks a lot!

Alan

I gave this a try, following the documentation from http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration

Unfortunately I have an error:

,---- | Establishing connection to tunnel:/usr/local/Cellar/dovecot/2.2.10/libexec/dovecot/imap -c ~/.dovecotzimbra.rc | Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) | Fatal: Couldn't load required plugins `----

This is the configuration file I tried: protocols = imap mail_location = maildir:~/.Maildir/zimbra:INBOX=~/.Maildir/zimbra/.INBOX mail_plugins = $mail_plugins sieve

plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/.sieve } The documentation says that one can only use the plugin with lda or lmtp. How do you use it with imap?

Anna,

I use lda.

Here are my relevant config files:

https://github.com/dhaley/feedyourbaby/blob/master/conf.d/15-lda.conf https://github.com/dhaley/feedyourbaby/blob/master/conf.d/90-sieve.conf

Hopefully that helps, although I'm guessing you've already figured it out.

Thanks. I found out how to call dovecot as a lda from fetchmail, but could not see how to do it from offlineimap. So I'm now using the following architecture, which works well in practice but is a little bit complex.

#+begin_example +------------+ +-----------+ imap sync +----------+ +----------------+ |mail clients|-----|remote imap|----------------------|local imap|------| mail clients | |(webmail, | +-----------+ (offlineimap) |(dovecot) | |(gnus, Mail.app)| | smartphone)| | +----------+ +----------------+ +------------+ V ^ | | fetch mail and filter it | | \______________________________/ | (fetchmail + dovecot lda) | | +------------+ +---------------+ |mail storage|-----| mail indexing | | (maildir) | | (notmuch) | +------------+ +---------------+ #+end_example

Alan

guess not what you want but using getmail maybe more easy

i.e like
