Re: Sieve for shared mailboxes

Bron Gondwana via Info-cyrus <info-cyrus@xxxxxxxxxxxxxxxxxxxx> · Sun, 20 Mar 2016 12:05:25 +1100

We don't use shared mailboxes or non-user sieve at all at FastMail, so it gets less testing than most things. I'd love to have contributions of good test cases to Cassandane from someone who knows exactly how this should work so we can make sieve good for the shared case too.

It's somewhat tricky now that FastMail is sponsoring the bulk of Cyrus work, obviously the stuff we use gets the most love!

Cheers,

Bron.

I have had mixed luck with direct mailbox delivery(+ addressing) and
    when I say mixed I mean mostly bad.

    I wanted to try using it for direct delivery of copies of all sent
    messages.

    I found I needed special permissions on all the mailboxes and
    duplicate delivery detection would not work in that configuration.

    So I dropped it.

    My guess would be that you may need to setup a shared mailbox or
    group mail account that would process the mail into the shared
    mailbox and then you could use sieve.

Sorry I wasn’t clear: we are using an alias with +plus addressing

I have the shared mailbox working just fine… it is
        only the sieve on shared mailboxes that is failing...

exit transport:

Sieve is
                  run as part of the mail delivery into the mailbox.

                  That would either be deliver or the lmtp interface.

                  If your users are dragging and dropping the messages
                  into the shared mailboxes then I don't believe that
                  you can have sieve run on the mbox to mbox transfer.

Greetings

I have been managing our mail domain
                      on a cyrus-imap (&exim) server since 2005 and
                      it has always been great for our ~150 users.

Of course, over-time more complexity
                      is always required and I have recently implemented
                      a few shared mailboxes (rather than just sharing
                      user mailboxes).

Inevitably, the users are now asking
                      for an auto-reply to be configured for some of
                      these shared mailboxes…

We are already using sieve scripts
                      (managed with Roundcubemail talking through the
                      firewall to timsieved) so it seems natural to use
                      this technology here too...

I have followed the instructions on
                      this page:

https://cyrusimap.org/imap/admin/sieve.html?highlight=sieve#managing-sieve-scripts

But the last step doesn’t seem to do
                      anything…

So I have a few related questions:

1) how can I query a mailbox to read
                      the flags set by mboxconfig?

2) has anyone got sieve working with
                      shared mailboxes?

3) is it possible to invoke a
                      sieveshell in the context of a shared mailbox?

I seem to have successfully created
                      the global scripts (a ‘global’ folder has appeared
                      in the sievedir) - just can’t seem to attach it to
                      a shared mailbox.

Many thanks!

Merlin
