Summary: Filter var for validating email is not validating
emails correctly

New Comment:
The format "usern...@box" for local networks IS allowed when the mail()
method is used. I quote RFC 5321: "local aliases MUST NOT appear in any
SMTP transaction." They say NOTHING about mail() method in the RFC.

A much better RFC-compliant regex has been committed now.

Finally having a look at this. Some of your cases are actually
incorrect
according to RFC3696/RFC5322
For example. ipinsteadofdom...@127.0.0.1 is not a valid email address
according
to the RFC. IPs in an email address must be in square brackets. So it
should
be ipinsteadofdom...@[127.0.0.1] for that one to be valid. This is
valid under
both RFC822 and RFC2822, but RFC3696 and RFC5322 updates those RFCs.
And you
can't have a port in it, so ipandp...@127.0.0.1:25 is invalid as well,
even if
you added the square brackets. Also we do not validate domains, so your
2
examples of invalid TLDs are not relevant.
I'll have an update of the baked in regex soon, but it sounds like you
need to
update the Kohana one as well.

Description:
------------
Filter_Var does not validate emails accurately enough, and false
positives are made. The regex needs improving - the regex we are using
in kohanaphp framework (with preg_match) is more accurate.
some more reading could be done here:

Reproduce code:
---------------
http://codepad.org/UIrhI5ep
Expected result:
----------------
All emails in $valid are valid, all emails in $invalid are invalid.
A far more accurate regex can be found here:
http://dev.kohanaphp.com/projects/kohana2/repository/entry/trunk/system/helpers/valid.php#L20
Actual result:
--------------
There are false positives and non failures.
