Hi, I would like to allow users to use any known "alias" of another user to grant permissions to their mailboxes. Here's the scenario: A user, with an internal name "example at 12345" and an alias "test at example.org". The domain "12345" is only used internally to separate the customers into different directories, therefore "anotheruser" only knows the address "test at example.org" grants folder permissions to "test at example.org". This results in the following: +-------------------------+--------------------------------------------+-------+ | from_user | to_user | dummy | +-------------------------+--------------------------------------------+-------+ | anotheruser at 12345 | test at example.org | 1 | +-------------------------+--------------------------------------------+-------+ But since the actual username is "example at 12345" the proper directory can't be found. I would like to achieve the following outcome, with the same user inputs: +-------------------------+--------------------------------------------+-------+ | from_user | to_user | dummy | +-------------------------+--------------------------------------------+-------+ | anotheruser at 12345 | example at 12345 | 1 | +-------------------------+--------------------------------------------+-------+ Is it possible to populate the to_user column with a more dynamic sql lookup instead of the dict lookup? Thanks in advance, Matthias
