# Mailboxes configuration ## `POSTMOOGLE_MAILBOXES_RESERVED` Space separated list of reserved mailboxes, example: ```bash export POSTMOOGLE_MAILBOXES_RESERVED=admin root postmaster ``` Nobody can create a mailbox from that list ## `POSTMOOGLE_MAILBOXES_ACTIVATION` Type of activation flow: ### `none` (default) If `POSTMOOGLE_MAILBOXES_ACTIVATION=none` mailbox will be just created as is, without any additional checks. ### `notify` If `POSTMOOGLE_MAILBOXES_ACTIVATION=notify`, mailbox will be created as in `none` case **and** notification will be sent to one of the mailboxes managed by a postmoogle admin. To make it work, a postmoogle admin (or multiple admins) should either set `!pm adminroom` or create at least one mailbox.
