Spam Level - 0%
We are a bunch of developers who hate receving junk email and have taken action against it
Our RBL is reputation based, meaning that we score each IP address in the world based on several factors.
We find that this is much more proactive compared to other RBL/DNSBL solutions out there who take a reactive response via methods such as spamtraps.
Since going public in early 2015, we have noticed many organisations start to use our RBL. Including several large ISP's and hosting providers
Our history is simple, not like our SPAM prevention, We started the RBL in 2014 as a private RBL for our own internal use. After we discovered that it had the potential to help others reduce spam, we decided to open it to the world.
How to use the RBL
The RBL base name is 'bad.psky.me'.
For Example, a lookup on 127.0.0.2
[email protected]:~$ dig 188.8.131.52.bad.psky.me +short 127.0.0.2 [email protected]:~$
The RBL conforms to RFC 5782
Currently, the RBL returns the following:
|NOERROR||The IP address is question is fine for sending mail.||Accept the message|
|127.0.0.2||The IP address in question has been seen with a high rate of spam.||Defer the message for later.|
|127.0.0.3||The IP address in question has been seen to have a very high rate of spam.||Reject the message at SMTP submission.|
