IMAP : Can't retrieve mails

[Ashitaka57]

Expected behavior

Mail app should retrieve all mails when creating a mail account in NC

Actual behavior

After creating the account in NC Mail, the connection is doing well, but the app can't retrieve mails because the commands sent to the mail server are not acknowledged by the mail serv.

Here the extract from Xeams Mail Server:
