Hi Benoit, Just an update from the Kopano community :
Kopano Gateway is an IMAP/POP3 Server, it does not listen to another IMAP/POP3 Server. You cannot use Apache James as IMAP/POP3 for Kopano. Only Kopano-Gateway can be IMAP/POP3 for Kopano. As you can see below[1], Kopano depends on Postfix as an SMTP server.
