Blacklist Profiles\JustSpam.org
These days and ages spam is still a major problem and there are lots of blacklists around for years, but the problem using them is that you are almost always at risk to block legit emails too, not just spam.
The JustSpam blacklist is an attempt to make it better and we strongly believe in providing a first class email reputation system free of charge.
Blacklist Zone(s)
dnsbl.justspam.org
Blacklist type
RBL: A RBL dnsbl is simply an anti-spam “black list” delivered via DNS which consists of IP addresses which are found in the body of the message. Specifically, there are the domains and IP addresses which spammers use to host their web sites.
Threat level/ delivery impact
Network Resource/ Deliverability Impact - Below are threats that could cause some significant delivery and reputational issues. At worst, you will experience continued delivery impacts and may be forced to purchase new sending domain and IP resources in order to achieve optimal deliverability.
Nomination
Automatic (upon receipt of a spam to a spamtrap mailbox).
Listing lifetime
30 days.
Notes
To remove an IP from our blacklist requires, it has to be removed from the other well-known and independent blacklists in first place.
As soon as we are the only blacklist that has an IP listed, it can be removed from dnsbl.justspam.org via our website by anyone that is in control of the IP.
Please make sure your system stopped spamming before you remove it from our blacklist. Another removal of a formerly removed, but new listed IP is not possible for the next 30 days. You have been warned.
Delisting guidance
