“An error occurred while sending mail. The mail server responded:
Invalid From address. Please see https://help.runbox.com/identities/.”

To send messages from an address that is not your main Runbox username or an alias address on the account that is sending the message you must verify ownership of that address otherwise our servers will not allow you to send the message and present an error similar to the one at the top of this page.

To verity you own an address you will need to create an Identity/Profile where the preferences are set to use the address you want to send from. In Runbox 6 these are called Profiles and are set up on folders.

The process in Runbox 7 is more streamlined and you can set up an Identity here.

The email address you use with a profile can be any address that you receive email for either on Runbox or elsewhere (e.g. a Gmail, Yahoo or iCloud address).

Note: Although profiles are set up on folders in the webmail interface, this set up in the webmail is also required if you send messages with an email program.

To set up a profile in Runbox 6:

  1. Create a folder that you can change the preferences on. You don’t have to use this folder for messages, but it does need to exist in your account for a profile to work. You can name it something useful that reminds you of what email address the folder/profile is for.
  2. Click on the folder you just created and then click on Preferences.
  3. Deselect the option that says “Use same preferences as Inbox” and click “Save Folder Settings” at the bottom of the page. This will let you customize the preferences for this folder.
  4. Enter the email address that you wish to use when sending mail using this profile.
  5. When you are finished, click the “Save Folder Settings” button at the bottom of the page and follow any instructions you are given in the interface.
  6. A verification email may automatically be sent to the address you chose in the preferences so that we can check you have access to that address. Once you have clicked on the link in the email the address will be verified and you will be able to use that address with your email program within 5 minutes.

The steps above are enough to complete what you need to do. For further information on aliases and profiles please see our Aliases and Profiles help page.
