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.
