Tomas Macek:
Hello, I'm trying to prevent my testing postfix installation 2.8.4 from
being
abused by emails that will go to the root@localhost email address.
I found out that it receives these messages accindetally, when I
tested my configuration.
The root@localhost must be accessible, when the mail comes from localhost
machine and not be accessible from the rest of the world - that's clear.
My server will receive email from many virtual domains.
I believe the right cfg place is smtpd_recipient_restrictions where I have
this:
smtpd_recipient_restrictions = permit_mynetworks,
check_recipient_access
This allows all mail from local networks.
http://www.postfix.org/postconf.5.html#permit_mynetworks
http://www.postfix.org/postconf.5.html#mynetworks
2) when I came from outside world, the restriction worked:
but when I came from 127.0.0.1, the mail was received - why exactly? But
Because of permit_mynetworks/mynetworks.

Many thanks to all of you guys!
But I have still one question...
What about if I'd would prefer to receive the mail for root@localhost from
just localhost and not from other places? = not from the rest of
mynetworks, not from outside of mynetworks - does this have any sense to
setup such a configuration? Is there any possibility to have sucha a
configuration?
Tomas
