As stated you may want to look into check_sender_access:
<http://www.postfix.org/postconf.5.html#smtpd_sender_restrictions>
so if I configure
/etc/postfix/access
with
[email protected] OK
[email protected] OK
[email protected] OK
[email protected] OK
[email protected] OK
and /etc/postfix/main.cf
with
smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/access, reject
will that block all email except that from the listed addresses?
Try it out and let us know it goes. Here is how you can test it:
telnet $mailserver 25
ehlo $client_host_name
mail from:<$sender>
rcpt to:<$to>
data
anything goes here
.
Test with both senders that are allowed and ones that are not,
and try both local and non-local to addresses.
