+### 2.1 Adding your account to an email client
+
+::: tip NOTE
+These settings can vary widely, if in doubt, please ask your system administrator / hosting provider for details.
+:::
+
+The username required to log in to your account is the **complete email address** itself, e.g. _[email protected]_.
+
+The type of account usually is **IMAP**, alternatively, POP3 is also supported. The ports for incoming and outgoing servers are always the default ones (143 for IMAP and 110 for POP3). Depending on the setup, you may use secure connection using SSL (Port 993 for IMAPs and 995 for POP3s).
+
+By default, the incoming (IMAP/POP3) and outgoing (SMTP) server should be the **domain from the browser address** you are using to access froxlor (without http(s):// and without any path/file information), for example _demo.froxlor.org_.

 ## 3. Forwarders
 
 To add an email forwarder, you first need to create an e-mail address or edit an existing one. From there (see [graph above](#_1-2-options-after-adding)) you can click on `Create forwarder`.
