Bagaimana cara mengecek server email terblacklist RBL melalui linux command line? berikut ini adalah software yang bisa anda gunakan untuk mengeceknya.

curl -O https://raw.githubusercontent.com/adionditsak/blacklist-check-unix-linux-utility/master/bl
chmod +x ./bl
mv ./bl /usr/bin

kemudian jalankan

# Use with domains or IP addresses
$ bl domain.tld
$ bl 8.8.8.8 # IP

# Pipe with other UNIX utils, eg. grep. Only blacklisted:
$ bl domain.tld | grep "blacklisted"

Contoh output

[root@usaweb user]# bl 139.99.23.62 | grep "blacklisted"
old.spam.dnsbl.sorbs.net [blacklisted] (127.0.0.6)
problems.dnsbl.sorbs.net [blacklisted] (127.0.0.6)
spam.dnsbl.sorbs.net [blacklisted] (127.0.0.6)

Untuk memilih beberapa rbl saja yang anda gunakan maka anda bisa langung melakukan editing pada file bl

nano /usr/bin/bl

Anda bisa hapus pada bagian
