AliCloud Enterprise Mail Setup: Admin Service Enablement + Client Security Password (incl. Foreign Trade Mail)
Complete configuration flow for AliCloud Enterprise Mail (including the 'Foreign Trade Mail' bundled with Alibaba.com International). Server addresses differ between the Standard Edition and Foreign Trade Mail. The admin must first enable 'Third-Party Client Access + IMAP/SMTP Service' in the console, then the user generates a 'Client Security Password'. When binding, fill in the Client Security Password, not the login password.
