Setting up Posteo in an email client (whether on PC, smartphone or tablet) is different for each client, however, you will always need the following details:
Server name: posteo.de
Password: Your personal password
Important: The connection to Posteo is always encrypted (STARTTLS, TLS or SSL).
The outgoing mail server (SMTP) requires authentication.
In case your email client asks: The password will be checked “normal” or “plain”. The password can also be transmitted unencrypted, because it is requested over a connection that is already encrypted.
The port settings depend upon the type of encryption:
With STARTTLS using port 587, or
with SSL/TLS encryption using port 465
With STARTTLS using port 143, or
with SSL/TLS encryption using port 993
With STARTTLS using port 110, or
with SSL/TLS encryption using port 995
The standard IMAP folders we have set up:
