Apple iPhone - iOS9 - Setup Guide

Are you using a new iPhone or the latest version of iOS? Please see our iOS15 SMTP server setup guide here.

Important Points

  • First you need to make sure the address(es) you will be sending from have been authorised on your account in our Control Panel.
  • These instructions assume your email account has already been setup and is collecting email correctly.
  • Take a note of any settings you change.
  • Only change the items specified - you should not need to change your incoming email settings.
  • These instructions are only for Apple iPhone / iPod Touch using iOS9 - for other email programs please see How To Setup AuthSMTP.
