Hello.
I easily constructed files:
/etc/postfix/relay_domains
/etc/postfix/mynetworks.cidr
Then I set:
@local_domains_acl = (
".$mydomain" ,
read_hash('/etc/postfix/relay_domains')
);
@local_domains_maps = @local_domains_acl;
In amavis log now I see a different tag ({RelayedInbound}):
Jun 28 09:24:05 av8 amavis[21699]: (21699-15) Passed CLEAN {RelayedInbound}, [xxx.yyy.zzz.uuu]:40882 [xxx.yyy.zzz.uuu] <aaa at example.com> -> <bbb at example.org>, Queue-ID: 0C98ED61C4, Message-ID: <8386362.10890651498634643768.JavaMail.www-data at v080>, mail_id: 0g9XxEmqcNPj, Hits: 2.2, size: 9179, queued_as: 7DAA4D61CA, 453 ms
Even in case neither example.com nor example.org are local domain.
What change made really implied?
For @mynetworks instead, I did not still set:
@mynetworks = @{ read_cidr('/etc/postfix/mynetworks.cidr') };
Because at the moment I have:
@mynetworks = qw( 127.0.0.0/8);
and:
$policy_bank{'MYNETS'} = { # clients in @mynetworks
bypass_spam_checks_maps => [1], # don't spam-check internal mail
bypass_banned_checks_maps => [1], # don't banned-check internal mail
bypass_header_checks_maps => [1], # don't header-check internal mail
};
So I fear that the change that you suggested me, avoid the SPAM scan for ALL mail departing from my real networks..
Is my fear justified?

RS
