We use Postfix on our gateways that only transport to destination
servers, they do not have any local users except for standard
system/root/admin accounts. How can I get Postfix to not allow senders
to use the hostname in their email address. Would it work and is it safe
to add such a REJECT to a sender_check hash file or another way to
prevent? This example below shows the sender using multiple addresses
including two of three with the hostname. When the end user receives the
mail, it shows from ene...@mx2.webtent.net....
