How to add another mailbox to multiboxi

You can add any mailbox that allows IMAP and SMTP access with a password: on your own domain, at o2, with a hosting company and with many other providers.

What you need

  • The IMAP and SMTP server addresses, ports and encryption type. You will find them in your provider’s help (usually under “mail program setup”) or in your hosting panel.
  • The mailbox password, or an app password if the provider offers one.

Step by step

  1. In multiboxi choose “Add a mailbox”, then “Other server”.
  2. Enter the email address, username (usually the full address) and password.
  3. Enter the IMAP and SMTP server and port. Most often: IMAP 993 with SSL/TLS, SMTP 465 with SSL/TLS or 587 with STARTTLS.
  4. Choose the provider’s country. If it is outside the European Economic Area, the wizard asks for your consent.
  5. The wizard checks the connection and shows the mailbox folders. Give the mailbox a name and a colour.

Good to know

  • Outlook.com, Hotmail and Microsoft 365 require Microsoft account authorisation (OAuth). We will add them later.
  • multiboxi connects only over encrypted connections and does not accept internal network addresses.

If something does not work

  • Wrong password message: check that you are entering the app password (without spaces), not your main password, and that IMAP access is turned on.
  • You can enter a new password later in the mailbox settings in multiboxi, without removing the mailbox.
