Can validation occur in Emp Self Service 'My Personal Email Address' page?

EBS HCM r12.2 rup18

We recently added the My Personal Email Address page to our self service application and I was wondering if there is a profile option or a way to add validation that the email address being added contains a domain and/or the ' @ ' ?

I've searched the Deploy Self-Service Capability Guide and see nothing. I've searched in the Knowledge Management and see nothing.

When I google the topic, it says 'In Oracle R12, you manage administrator profile values through the Setup and Maintenance work area, specifically under the Manage Administrator Profile Values task.' But that's not true as this is OCloud navigation.
