adding filter for site domain email check

Was happy to see the new special tags feature added and the new special tag for _site_admin_email.

I would like to request a similar one for the network admin (on a multiuser site); that’s what I use as the FROM field in contact form 7.

I can actually achieve this with a custom tag, EXCEPT that contactform 7 complains when it comes to checking if the email address is the same as the server.

Can i suggest that a filter be added for checkign if email is in site domain?

It would be added in formatting.php in function “function wpcf7_is_email_in_site_domain( $email ) ” and the code would look like this near bottom of function:

change from “return false” to
” $result = false;
$result = apply_filters( ‘wpcf7_is_email_in_site_domain’, $result, $email );
return $result;
”

In this way, we could override the result of the domain email check.
