Comment (by tusharbharti):
Hi @jdeep, for list of emails you can use
https://github.com/WordPress/gutenberg/pull/70709/files#diff-
97d7e31909f55f8a55039aba5abc9c00942ee379595ab293be5accdad0886e1d
though some changes are that
`1234567890123456789012345678901234567890123456789012345678901234+x at wordpress.org`
will counted as valid even though it isn't because when we had a
discussion regarding email lengths it was agreed upon to not break
previous supported email listing that had local part more than 64 chars
long.
