Comment:

 `is_email` function does accept email addresses with the plug sign.


 {{{#!php
 var_dump(is_email('info+admin at example.com'));
 // info+admin at example.com
 }}}

 Note the function returns the original email address on email addresses
 this function deems correct. If the `is_email` function returns false for
 you on such email address, it is possible that a plugin makes so by using
 `is_email` filter.
