I’ve set up Email client on Outlook 365 and it works well without “server requires an encrypted connection (SSL/TLS)”. When I check this option it gives an error: “We couldn’t connect to the incoming (POP) server using the specified encryption method.”
On Hestia Edit Mail Domain I checked Spam Filter, DKIM, Enable SSL for this domain ->Use Lets Encrypt to obtain SSL certificate. Also SMTP Relay Port 110
