Σχετ: Do not use RBL for my networks

[Peter Tselios]

No, I **DO** want spam checks for outgoing email, I just do not want RBL and PBL checks. 99% of false positives are due to PBL SBL checks. So, I just want to avoid that (and for a few days/weeks only).

Would the trusted_networks do the trick?

You want a final (sum) score 0 for such mail, or just score 0 for RBL rules?
I'll just address the former case here.

Perhaps the most straightforward way is to disable spam checks
entirely for mail originating from your networks, using a policy bank
triggered by mail originating from an internal network:

@mynetworks = qw(
  0.0.0.0/8 127.0.0.0/8 [::1] [FE80::]/10
  169.254.0.0/16 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16
  ... list all your internal IPv4 and IPv6 networks ...
);

$policy_bank{'MYNETS'} = {  # mail originating from @mynetworks
  originating => 1,
  bypass_spam_checks_maps => [1],
};


If you also have roaming authenticated mail submissions,
this needs a somewhat more complex setup, as Postfix needs
to use a dedicated amavisd port for such mail, so that
amavisd can attach a dedicated policy bank to it.

On the SpamAssassin's side, make sure to list all your
internal networks in trusted_networks and in internal_networks.
A more complex site may also need to configure msa_networks.
