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:

--8<---------------cut here---------------start------------->8---
protocols = imap
mail_location = maildir:~/.Maildir/zimbra:INBOX=~/.Maildir/zimbra/.INBOX
mail_plugins = $mail_plugins sieve

plugin {
  sieve = ~/.dovecot.sieve
  sieve_dir = ~/.sieve
}
--8<---------------cut here---------------end--------------->8---

The documentation says that one can only use the plugin with lda or
lmtp. How do you use it with imap?

Thanks,

Alan
