NethServer Version: 7.8.2003
i enabled the mail app of nextcloud and tried to connect a user to its dovecot mail account running on the server. Whatever I tried, I always get the following failure message:
[mail] Fatal: Creating account failed: Could not connect to IMAP: Could not open secure TLS connection to the IMAP server.

The connection works fine with SOGo, Thunderbird and some other mailclients.
