Mail settings are not accessible for a subdomain, but it is possible to access them via a main at Domains > example.com > Mail settings > "..." > foo.example.com
Activate mail service on this domain,
an error occurs:
Error: There is no mail service for domain with id = 3. It must be created before call update
Mail related functionality is not accessible for subdomain, however not supported functionality is accessible in user interface.
This is Plesk bug with ID # PPPM-6133. It's planned to be fixed in future Plesk updates.
There is no possible workaround at the moment.
