Alternatives to CBLabuse.org for delisting blacklisting

Currently resolving a WAN virus issue where the domain email is getting blacklist every day.

Whilst getting the WAN safe we're having to delist the domain so genuine emails can flow. I've been using http://cbl.abuseat.org which has been working fine but today their server appears to under strain and I get "The website is too busy, please try again later." when trying to delist.

Are there any other free services out there which delist your domain/IP from being black listed?

De-listing is handled by each RBL maintainer.  Find out where you are listed, then apply to that list's site.

Doesn't make sense to attempt de-listing if you are still in the midst of a cleanup.  Some services will re-list you for longer and longer periods  for falsifying the application to de-list.

Try MXtoolbox.com to check the most-used RBLs.

Also, move your outbound mail traffic to a different public IP than you use for general internet access.

Then, shut down all SMTP outbound traffic except for an explicit list of your authorized SMTP relays.  That way, if your users start pumping out spam, your relays will not get blacklisted.

this wiki comparison is a good starter summary, which include cbl.abuseat.org or use Spamhaus XBL list directly. But do note the caution from CBL on "The Spamhaus XBL (or SBL-XBL or Zen) is a full superset of the CBL, and you SHOULD NOT USE BOTH DNSBLs at the same time."

See the CBL FAQ on "Other DNSBLs?' http://cbl.abuseat.org/faq.html

Other candidate include ThreatSTOP, DNS-BH or DNSBL
