I can't seem to find any documentation on the meaning/syntax of the "pattern" variable in map sections that are found in dovecot-dict-sql.conf.ext for example. I am trying to setup shared folders.

I need to understand how they work because I can't use the example in http://wiki2.dovecot.org/SharedMailboxes/Shared. This is because in my PostreSQL table users are not a single column but two columns with the local and domain part

I couldn't find anything myself even after skimming through the code so I created PostgreSQL rules to circumvent the problem. Here they are in case anyone has the same problem.

This is the view I created for listing shared folders:

CREATE VIEW view_shared_mailboxes AS SELECT shared_mailbox_local || '@' || shared_mailbox_domain AS "shared_mailbox", shared_to_local || '@' || shared_to_domain AS "shared_to", 1 AS "dummy" FROM shared_mailboxes;

And these are the rules to enable INSERTSs and DELETEs:

CREATE RULE view_shared_mailboxes_insert AS ON INSERT TO view_shared_mailboxes DO INSTEAD INSERT INTO shared_mailboxes (shared_mailbox_local, shared_mailbox_domain, shared_to_local, shared_to_domain) VALUES (split_part(NEW.shared_mailbox,'@',1), split_part(NEW.shared_mailbox,'@',2), split_part(NEW.shared_to,'@',1), split_part(NEW.shared_to,'@',2));

CREATE RULE view_shared_mailboxes_delete AS ON DELETE TO view_shared_mailboxes DO INSTEAD DELETE FROM shared_mailboxes WHERE shared_mailbox_local = split_part(OLD.shared_mailbox,'@',1) AND shared_mailbox_domain = split_part(OLD.shared_mailbox,'@',2) AND shared_to_local = split_part(OLD.shared_to,'@',1) AND shared_to_domain = split_part(OLD.shared_to,'@',2);
