that is policy, becurse local senders will not use port 25
fyi, I do have some clients that send mail without authentication on port 25
within their company network, and I hardly have chance to force those into
reconfiguring.
Of course, I'm not talking about those in this thread.
hope this clear it, mail from: can not be ensured to be non forged by
sasl auth, without a milter to protect this policy, if postfix can do
this aswell i like to know aswell
you apparently mean header From: which can be required or fixed by using
recently mentioned "vrfydmn" milter.
but let's go step after step.
