Autocomplete rule to validate email domain using a User-Defined Table (UDT)

Summary:

We have a requirement to validate email domain in Contact Info page using autocomplete.

While there is a list of these domains (150+ email domains), our client is saying that this list is dynamic and the number will be increased over time.

Can we use a UDT to meet this requirement? If not, how do we achieve this using Object Function?

Criteria:

IF Email Type is in Home or Other

AND Email contains email domain from the list (UDT or could be an object function)

THEN throw an error message

Appreciate if you could share a sample validation rule. Thanks a lot!
