So we are "regexing" emails again?

What should be valid email addresses according to RFC 2822 [1]:
!#$%&*+-/=?^_`{|}~@example.com
"@"@example.com
Not valid email addresses:
"\"@example.com
@@example.com
- -@xxxxxxxxxxx
Valid email addresses according to the Multipurpose Internet Mail
Extension (MIME) [2]:
ä@example.com
Ã(c)@℞.com
Yes, I know I'm going to hell, but it serves well for most purposes. In
the future when I actually see people use those kind of email addresses
then I'll update it.

basically if it has 1 or more printable chars followed by an @ followed
by 1 - 63 printable chars followed by a period followed by a valid
domain extension it's good; that's simple regex :p
