Mail on an everjust.app tenant is a from-scratch webmail stack on `everjust.mail.*` models. It is not Odoo Discuss, not chatter and not `mail.mail`. You work it through `mailbox_list`, the `inbox_*` tools and the `mail_*` tools, as the Odoo user your connection runs as. These tools check their input, cap their output, never delete for good and leave a readable audit row. Connecting, scopes and `confirm`: [[everjust-agent-mcp]].
