About This Guide
The Inbox.ru email settings on this page were last verified on April 12, 2026 against the provider’s official help documentation, publicly available postmaster resources, and independent user setup reports. Email server configurations rarely change once established β most providers issue major updates only every one to two years, typically tied to phasing out unencrypted protocols or migrating to new mail infrastructure. SMTPedia re-verifies these settings quarterly and after any announced changes from Inbox.ru. If you find a discrepancy between what is documented here and what Inbox.ru currently requires, please report it so we can update the reference.
