The only correct regex for email is:
.+@.+
So long as the address has a local part, the at sign, and a hostname, it’s a valid email address.
Whether it goes somewhere is the tricky part.
Sorry, this is not a correct regex for an email address.
Sending using ‘mail’ on a local unix system? You only need the local part.
STOP VALIDATING NAMES AND EMAIL ADDRESSES. Send a verification email. Full stop. Don’t do anything else. You really want to do this anyway, because it’s a defense against spam.
I think it’s fair to prevent users from causing mail sent to your internal systems. It probably won’t cause any issues getting mail to the machine inbox for (no domain name), but it reasonably makes security uneasy.
