I need validation in such a way that it validates each mail address is in mail format and one mail address per line.
example : "test@test.com"
"test2@test.com"

If there are any errors then throw validation error ,if all email addresses are in mail format then how to pass these mailaddresses to integration where body is

"emails": "test@test.com, test@test.com" and save the response of this mailsaddress in DB
