Find mail-client connection settings
Use the mail endpoint and TLS identity configured by your provider.
Before you begin
A mailbox and confirmed server hostname, ports and encryption modes.
Use the controls offered by your installed version and account permissions. This guide describes the workflow; it does not grant additional access.
Follow the steps
- Use the full mailbox address as username unless instructed otherwise.
- Use the published hostname covered by its certificate for encrypted IMAP/SMTP.
- Enter actual provider ports and TLS modes rather than guessing from screenshots.
- Enable outgoing authentication when required.
- Test sending and receiving separately.
Check the result
The client authenticates to the correct service and validates its certificate.
If something goes wrong
A raw IP may not match a hostname certificate. Localhost and 127.0.0.1 refer to the client's machine, not your hosted mailbox.
