Question

How to delist blacklisted IP Address

Asked by: Atouray

For over some weeks now I can't send mails using one of my ISP.  When ever I send a mail it bounce back with these lines

Your message did not reach some or all of the intended recipients.
      Subject:      test
      Sent:      1/5/2009 4:37 PM

The following recipient(s) cannot be reached:

      'name@domain.com' on 1/5/2009 4:37 PM
            451 Blocked - see http://www.spamcop.net/bl.shtml?00.00.00.00 (IP Address)

and when I send the same mail with another ISP connection it goes.

When I clicked the spamcop.net link it takes me to a page with these messages:

Query bl.spamcop.net - IP ADDRESS
(Help) (Trace IP) (SenderBase Lookup)

IP ADDRESS listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 18 hours.
Causes of listing

    * System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Additional potential problems
(these factors do not directly result in spamcop listing)

    * DNS error: IP ADDRESS has no reverse dns

Because of the above problems, express-delisting is not available
Listing History
In the past 70.8 days, it has been listed 23 times for a total of 60.2 days.

and my host has confirmed to me that they don't ve reverse DNS.

What should i do now?

If they don't have reverse-DNS for their dynamic addresses, there isn't much you can do about it.

Lots of spam-blocking software won't allow connections from dynamic addresses anyway, so you should really be using the outbound SMTP server at the ISP.

Use the ISP's outbound SMTP server.
