It is called "local-part". And yes, RFC 5321 and 5322 have a pretty
comprehensive spec for it.
The following is a valid e-mail address for example:
"alert('Ohhai')"@43-1.org

It seems most special characters like ".", "-", "+", "_", "#", "$" are
permitted in the username part.
And even ___username...@domain.com is right (like my sender account).

Hello,
Is there the username specification for email system?
It seems most special characters like ".", "-", "+", "_", "#", "$" are
permitted in the username part.
And even ___username...@domain.com is right (like my sender account).
So I was confused.
Thanks.
