Comment(by mpatel):
[http://www.dominicsayers.com/isemail/ These]
[http://fightingforalostcause.net/misc/2006/compare-email-regex.php sites]
have test results for several increasingly complex validators.
It seems the main remaining sources of false negatives in `is_valid_email`
are
* Other special characters not in quoted strings:
`!def!xyz%[email protected]`
* IP addresses: `first.l...@[12.34.56.78]`,
`first.l...@[ipv6:1111:2222:3333::4444:5555:6666]`
* Quoted strings: `first."mid\dle"."l...@st name"@example.com` (`\` can
escape anything but must escape something)
* Top-level-domains (TLDs) of any length: `[email protected]`
* Comments, possibly nested: `a(a(b(c],d(e(f],],g],h(i],j],@example.com`
