in order to set up e-mail archiving with mailstore, I need to configure journaling mode for the mailserver. Means, that a copy of every e-mail (in- and outgoing) of a mailbox is sent to the mailstore gateway. How can I do that (setting per client preferably)
If you want to set it globally, you must set an auto bcc in the Postfix main.cf file for incoming and outgoing mail. If you want to set it up per mailbox, use the mailbox's bcc settings.
