Whitelist Domains in a file

[bjoernh]

I had Maddy running for two years now. It worked like a charm! I would like to configure a whitelist for some Mailservers that are poorly configured and skip the checks for this domains.

So my attempt is to use the example from the docs and modify it

smtp tcp://0.0.0.0:25 {
    debug yes
    limits {
        all rate 20 1s
        all concurrency 10
    }
    source_in file /data/whitelist {
        destination mydomain.com {
            deliver_to &local_mailboxes
        }

        default_destination {
            reject 521 5.0.0 "User not local"
            }
    }

    dmarc yes
    check {
        require_mx_record
        dkim
        spf
    }

    

    source $(local_domains) {
        reject 501 5.1.8 "Use Submission for outgoing SMTP"
    }
    default_source {
        destination postmaster $(local_domains) {
            deliver_to &local_routing
        }
        default_destination {
            reject 550 5.1.1 "User doesn't exist"
        }
    }
}

my whitelist file /data/whitelist contains this

domain1.com
domain2.com

But it isn't working as expected. Mails from domain1.com are still checked. How can I archive this kind of whitelist?

source_in checks the entire address, you need to define a pre-processing step to strip away the local part (before @) before file lookup.

# at top-level
table.chain smtp_whitelist {
  step regexp "(.+)@(.+)" "$2"
  step file /data/whitelist
}

source_in &smtp_whitelist {
   ...
}
