We are working on a POC in 8.4 version and are trying to validate email using the Pega OOTB edit validate rule ValidEmailAddress. We found that this OOTB verifies if the email contains @ or not but check for the domain is not available.
ex: abc@abc accepted as a valid email address.
While analyzing the OOTB we found that it is as per the RFC822 guidelines.
Trying to understand what is RFC822.??
Any inputs would be helpful.
