    Postfix hasn't this capability. Either use Sendmail or Exim.

    You certainly allow relaying based on LAN IP/mail addresses. You send by
    Squirrelmail? Well, that is localhost then and of course allowed to
    relay/send.

    Possible with something like that:

    <Location /webmail>
        RewriteEngine on
        RewriteCond %{SERVER_PORT} !=443
        RewriteCond %{SERVER_ADDR} =192.168.0.90
        RewriteRule ^.* - [F]
        ErrorDocument 403 https://192.168.0.90/webmail/
    </Location>
