GMX turns IMAP off by default. Switch it on in GMX's settings, then use these servers in your mail app.

Turn on IMAP in GMX
- Open settings. In GMX's web mail, open the Email tab, then Settings.
- Allow POP3 and IMAP. Choose POP3 & IMAP, tick the option for external access, and save.
Use GMX in GotEmail
In GotEmail, choose Add Account, then Other (IMAP), and type the settings from the table: the IMAP and SMTP servers, their ports and encryption, your username and password. GotEmail checks them as you sign in and tells you what to fix if a server says no.
Good to know
- GMX switches POP3/IMAP access off again if you don't use it for a long time.
- Your mail app must use TLS 1.2 or 1.3; GMX no longer supports older versions.
Checked against GMX's own help pages: GMX IMAP server settings, Activate POP3 and IMAP.
