What can I control on Mailcow from inside Odoo?

The connector talks directly to the Mailcow REST API /api/v1 and covers four core areas: *mailboxes* (create, edit, delete, tags), *domains*, *aliases* (including time-limited aliases) and *domain policies*. You manage all records as normal Odoo models and a sync service keeps Odoo and Mailcow consistent. /Code reference:/ services/mailcow_connector.py lines 13–80+: class MailcowMailboxAPI with methods create_mailbox , edit_mailbox , delete_mailbox , get_aliases , get_time_limited_aliases , add_alias . Models under models/ : mailcow_mailbox.py , mailcow_domain.py , mailcow_alias.py , mailcow_domain_policy.py .

How do I configure the connection to my Mailcow server?

Only users in the *"Mailcow Manager"* group are allowed to configure the connection. Under /Settings → Mailcow/ enter your *API URL* (your Mailcow web UI URL) and the *API Key*. The /"Check connection"/ button performs a live probe against /api/v1/get/mailbox/all . Sync actions are unlocked only after a successful check. /Code reference:/ models/res_config_settings.py lines 9–16 (config parameters mailcow.api_url , mailcow.api_key ), lines 28–31 (group check) and lines 33–54 ( action_check_mailcow_connection ).

Who can see which Mailcow data in Odoo?

The module ships a dedicated permission group *"Mailcow Manager"*. All Mailcow menus (mailboxes, domains, aliases) are visible only to members of this group — standard users see nothing. When configuration values are written, an additional server-side check enforces that only managers may persist them. /Code reference:/ views/menus_views.xml lines 11–26 (every menuitem carries groups="mailcow_connector.group_mailcow_manager" ); models/res_config_settings.py lines 28–31 ( set_values with has_group check + UserError ).

How is a full Odoo ↔ Mailcow data sync triggered?

The /"Sync All"/ button in Mailcow settings calls mailcow.sync.service.sync_all() . Prerequisite: the connection was previously verified (flag mailcow.connection_verified = 1 ). On top there is a scheduled cron that runs the sync automatically; the cron XML record lives in data/ir_cron.xml . /Code reference:/ models/res_config_settings.py lines 56–71 action_mailcow_sync_all ; the manifest __manifest__.py line 46 loads data/ir_cron.xml .

Are custom attributes on mailboxes supported?

Yes. You can set arbitrary custom attributes per mailbox — the connector posts them to the Mailcow endpoint /edit/mailbox/custom-attribute . This is useful, for example, to tag billing or cost-center metadata on a mailbox without adding extra fields on the Mailcow side. /Code reference:/ services/mailcow_connector.py lines 60–67: set_custom_attributes(self, address, attributes: dict) → POST to /edit/mailbox/custom-attribute with {"attr": {"attribute": [...], "value": [...]}, "items": [address]} .
