I read this technical report but I don't understand if is necessary to change the DNS for "autodiscover" and "autoconfig" records or just "enable mail autodiscover" for each domain in the Plesk control panel:
support.plesk.com
Is necessary to add manually these two new records "A"?
autodiscover A IP-server
autoconfig A IP-server
Also, how can I change the parameters that the email clients set automatically?
E.g. How can I change the "autodiscover" instruction sent to the email client for the port 25 with 587?
Thanks
