I'm using a Postfix and a Mailscanner setup.<br><br>How do I only allow access to certain email alias addresses in <br>/etc/postfix/aliases based on the sender domain or ip.<br><br>In this case my own domain is <a href="http://example.com">
example.com</a> and it contains<br>an examplealias which points to certain local users. Users<br>from outside the network/domain may not send email<br>to that alias.<br><br>Only allow<br> Mail to: <a href="mailto:examplealias@example.com">
examplealias@example.com</a><br> From: <a href="http://example.com">example.com</a> or <a href="http://192.168.0.0/24">192.168.0.0/24</a><br>(if its a ip block or domain block doesnt matter)<br><br>Recejet all other senders trying to send email to
<a href="mailto:examplealias@example.com">examplealias@example.com</a><br>(It would be nice if one could return an SMTP error code if the sender is not allowed<br>to send to the alias.)<br><br>How do I do that?<br><br>Thanks for your input!
