Description:
------------
Some email addresses that are obviously wrong, pass the validation with
FILTER_VALIDATE_EMAIL.  You can not have a top level domain with one
character only.

as reported in bugreport http://bugs.php.net/bug.php?id=47879 

nice to have the option to:
select whether it has to check if its an internal address or a non internal address.

Reproduce code:
---------------
var_dump(filter_var("x@y.z", FILTER_VALIDATE_EMAIL));


Expected result:
----------------
bool(false)




Actual result:
--------------
string(5) "x@y.z"

Did you not read the comment on 47879?  You can have single-letter top-levels in internal mail systems.

[2009-04-27 07:30 UTC] m dot vdhulst at puredutch dot nl

[UPDATED]

Reproduce code:
---------------
var_dump(filter_var("x@y", FILTER_VALIDATE_EMAIL));

Expected result:
----------------
bool(false)

Actual result:
--------------
string(3) "x@y"

as shown this will result to true, but this is not a valid email adress. 

I would like to see additional flags, f.ex.: FILTER_VALIDATE_EMAIL_INTERNAL, respectively FILTER_VALIDATE_EMAIL_INTERNATIONAL.

[UPDATED2]

Maybe my description is a bit wrong. I would like to have additional validation flags like FILTER_FLAG_EMAIL_INTERNAL, FILTER_FLAG_EMAIL_INTERNATIONAL so that the filter can also be used to check against only international email adresses (with a dot after de @).

(sorry about the noise, I tried to edit my original bug description, but this doesn't work. Neither can i re-open the feature request)
