Set up your Posteo.de | The Correct IMAP and SMTP Settings

How to access your Posteo.de Account from any Email app using the right configurations

Instead of using Posteo.de's webmail interface, you can use mobile and desktop email apps like BlueMail, Outlook, Apple Mail, or Mozilla Thunderbird. Desktop email apps offer multiple features along with quicker access, and your emails are still available on your computer or mobile phone even when you're offline.
