Blacklist Zone(s)
Blacklist type
URIBL: A URI dnsbl is simply an anti-spam “black list” delivered via DNS which consists of domain names and 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.
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), with extensive whitelists and filtering to prevent false positives.
Listing lifetime
Blacklist data lives about 5 days so if you are wrongly blacklisted or if you had a virus and fixed he problem you will automatically be delisted 5 days after the spamming stops.
Notes
The black list catches spam only servers. Generally these include virus infected users who are being used as spam servers. The list is generated by honeypot accounts and spammer's behavior where spam is caught be dong things that only spammers do. We have developed a lot of unique methods of detecting spam based on the behavior of the spammer. We can detect spammers by the way they try to deliver email rather than by the content of the message.
Delisting guidance
