Hi all,
we are using an exchange 2016 on premise and a Sophos UTM 9.707-5.
We want to realize that external clients can connect to their mailboxes via IMAP but not sure how to do that. Do we need to setup WAF for this or is it only possible via port forwarding (DNAT).
Thanks in advance and greetings
