[SOLVED] Mail delivery to shared folders

[gurubert]

I am coming from a qmail + dovecot installation.

There we had aliases with delivery instructions to Maildirs that acted as shared IMAP folders.

How do we achieve this feature in Zimbra?

How do I setup an alias / DL for a specific mail folder?

To answer my own question:

Create an alias for the account that holds the shared folder.

In the account create a mail filter rule:

if anyof (header :contains "Received" "alias@example.com") { fileinto "path/to/folder"; stop; }

There is always a Received: line in the email headers that contains the alias address.
This avoids missing emails when filtering for To or Cc and the alias address was on Bcc.
