# spamip

spamip is a command line tool that adds an IP to a bind zone file in DNSBL format

## Getting Started

All you need is a file with this header, in my cast it's located in `/var/bind/pri/localhost.zone`

```
$TTL 1W
@       IN      SOA     localhost. root.localhost.  (
                                      2009121301 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      604800     ; Expire - 1 week
                                      86400 )    ; Minimum
@               IN      NS      localhost.
@               IN      A       127.0.0.1

@               IN      AAAA    ::1
;------------------------------------------------------------------
2.0.0.127       IN      A       127.0.0.2
                IN      TXT     "example.com test record"
3.0.0.127       IN      A       127.0.0.3
                IN      TXT     "example.com verified spam source"
10.0.0.127      IN      A       127.0.0.10
                IN      TXT     "example.com confirmed DUL range"
;------------------------------------------------------------------
```

and this part appended to your /etc/bind/named.conf

```
zone "localhost" IN {
        type master;
        file "pri/localhost.zone";
        notify no;
};
```

Then check your message source (in Thunderbird that's CTRL+U) for the spammer's IP you'd like to block
and write `spamip add 1.2.3.4` where 1.2.3.4 would be the spammer's IPv4 address.

and finally reload bind (`systemctl reload named.service` or bind9.service or bind.service)

The postfix part is simple:
```
smtpd_recipient_restrictions =
        reject_unknown_sender_domain,
        reject_unknown_recipient_domain,
        reject_non_fqdn_sender, 
        reject_unauth_pipelining,
        permit_mynetworks,
        permit_sasl_authenticated,
        reject_unauth_destination,
        reject_rbl_client localhost
```

et vóila, your own DNSBL.
