DNS blacklist removal

carlos.nino
Hi,

I have a problem with a mail server. I can't send mails to some 5 or 6 addresses because they are returned with something like this:

The original message was received at Thu, 15 Feb 2007 13:07:50 +0100
from root@localhost

----- The following addresses had permanent fatal errors -----
jlma@grupoaepsa.com
(reason: 554 The IP Address of the sender (194.224.106.227) was found
in a DNS blacklist database and was therefore refused.)

----- Transcript of session follows -----
... while talking to mail.grupoaepsa.com.:
>>> RCPT To:<jlma@grupoaepsa.com>
<<< 554 The IP Address of the sender (the mail server's IP) was found in a DNS
blacklist database and was therefore refused.
554 5.0.0 Service unavailable

It's been blacklisted, but only for some addresses.
How can I remove this IP from the blacklists?

    Firstly you need to know which blacklist has got you listed - as ultimately you're going to have to talk to them (or at least know whether or not you'll be able to talk to them)

    Your IP address is unlikely to have been added to a list accidentally, so you either have dodgy neighbours or dodgy controls on your systems. Both of these are within your control and should be your top priority if you're serious about your email.

    Contact the host that's bouncing the mail. Ask them why they have bounced it with a VERY vague message... "was found in a DNS
    blacklist database and was therefore refused" and find out which DNSBL they subscribe to.

    Do some general research on http://www.dnsbl.info/ to see how many places list your address. If the search results light up bright red all over the place then either A) get a new career , or B) start looking for some new service providers.

    I've had a similar problem with my SBS server at one of the locations that I maintain. Apparently, the whole block of IP's that our ISP is responsible for had been blocked by apews.org. The easiest way around it for me, since we couldn't get another ISP at our location, was to use a mailhop service from dyndns. I just added the domains that were blocking us to the mailhop relay, and email resumed.
