Why do you use DNS blacklists?
We use multiple providers of DNSBL, or DNS blacklist (also commonly called RBL or Realtime blackhole list), services to check IP addresses against lists of known IP addresses that have been recently used for spamming or as attack vectors for other nefarious activity. We do not control these lists, nor can we remove a listing on your behalf.
We also submit addresses we have found to be sources of such activity for inclusion in these blacklists.
How do I request removal of my IP address?
For your convenience, here are some (but not all) of the DNSBL providers we use and their lookup pages.
You can also use the Multi-RBL lookup tool to check a large number of blacklists.
My IP address keeps getting listed, what can I do?
Unfortunately, users of some ISPs may find themselves repeatedly listed through no fault of their own. We allow most DNSBL checks to be bypassed by users who authenticate to their account while connecting. See the Login-on-connect and SASL guides for more information.
