If you are using an email client such as Outlook, Apple Mail or Thunderbird you might find our Recommended Email Clients page useful as it contains guides to setting up some popular email clients.

If your email client does not automatically detect the correct settings for your Runbox account, or if you need to manually set up your client, you will need the server settings below to configure it.

If you’re unsure about the connection method to use in your email client, you can read more about IMAP, POP, and SMTP first.

We always recommend using a secure connection to our servers as this protects your username, password and email content from being intercepted whilst it is being passed between your computer and our servers.

Secure/Encrypted IMAP, POP and SMTP

Incoming Mail Service Settings

Incoming Server (IMAP):  mail.runbox.com
Port: 993
Secure/Encrypted Connection – TLS/SSL: Yes/On
Authentication: Password

Incoming Server (POP): secure.runbox.com
Port: 995
Secure/Encrypted Connection – TLS/SSL: Yes/On
Authentication: Password

Outgoing Mail Service Settings

Outgoing Server (SMTP):  mail.runbox.com

Port: 465 with TLS/SSL
Port: 587 with STARTTLS

Secure/Encrypted Connection: Yes/On
Authentication: Password

Note: Port 465 may offer better connection security than port 587. However, in some cases port 587 may be more compatible with email clients. For information about the differences between these ports, please see our help document about Connection Encryption.

Username Formats

Runbox Addresses

If you only use a Runbox email address that looks like the one below, then your username is the first part of the email address before the @ symbol.

Email address: username@runbox.com (also @runbox.no, @runbox.us etc…)
Username:  username

Using your own Domain

If you signed up to your Runbox account using your own domain name then your username will be as follows:

Email address: username@domainyouown.com
Username:  username%domainyouown.com (note that the @ symbol changes to a % symbol)

Please Note: If you used your account using an @runbox email address before you added your own domain name, then your Runbox username will not have changed and will be the same as for @runbox email addresses (see above).
