Hello!

>> my mail server is Lotus Notes version 10.0.1
Please note, that Plesk does not support Lotus Notes mail server and it seems you are using external mail server. Also, according to provided information you're using external DNS provider. In this case there is nothing to configure in Plesk.

Here you could find general instructions on how to configure DKIM and SPF records:
