    First of all, if your IP landed on some blacklist, in most cases it
    means that some "junk" got out from your IP, either through your
    exchange server or directly (if you didn't properly set your firewall
    rules)

    Second, there's no "common method" to remove a given IP from
    whatever DNSBL, so it would be useful to know which lists your
    IP is on or, better, to know your IP address

    Third, before asking for removal, you should ensure to check
    why your IP was listed, investigate about the issue and ensure
    to solve it, otherwise you'll get re-listed in a short and, usually,
    the removal requests aren't accepted if repeated too often

    Fourth, the "I need help urgent" isn't a good way to get help,
    people here is volunteering his time, so, if your problem is
    really urgent, you'd better place a call to some local consultant
    and have them solve your issue

    Agree with ObiWan.

    Just for your convenience, I would like to provide you a related thread for you to follow.

  • In addition to what ObiWan said, put your IP into one of these tools:

    http://www.mxtoolbox.com/blacklists.aspx

    http://www.robtex.com/

    You will get a list of DNSBLs that are blacklisting you.

    Next check the information these lists give you. This will help you understand why you are listed.

    With that info you can start fixing the problem at your server. Once that is done, you will need to check with each DNSBL about their delisting procedure.

    since we're at it, here are a couple more tools

    http://multirbl.valli.org/lookup/

    http://www.senderbase.org/

    Next check the information these lists give you.
    This will help you understand why you are listed.

    Yes, DNSBLs usually show an URL related to a given listed
    IP and reading the informations found there will (in most cases)
    tell why the IP was listed and also give instructions about how
    to fix the issue and request a de-listing

    With that info you can start fixing the problem at your server.
    Once that is done, you will need to check with each DNSBL
    about their delisting procedure.

    Totally correct; notice that, as I wrote, some lists allow to use
    some online tools (pages) to automatically de-list an IP, but
    those tools run some checks, so, if one delists an IP but the
    IP is then found "guilty" again, the second delist will take more
    the third may take up to a week and the fourth will require a
    mail contact with the DNSBL admins (that is, the tool won't
    allow to request an automatic delisting anymore) - this means
    that BEFORE requesting a delisting one should ensure to
    solve the issue which caused the listing

    thread for you to follow.

    Thanks; just a bit more infos

    Whenever setting up a mailserver (whatever mailserver, not just
    exchange) - and I mean an internet facing one, there are some
    rules to follow; more or less...

    * If the IP on which you published your mailserver (aka the IP it uses
       to send emails) is the same used to "go out to the internet" (e.g.
    surf
       the internet etc...) you'll need to configure your perimeter firewall
    to
       block outbound traffic to port 25/tcp and only allow it from the
    mailserver
       this will block infected machines sitting on the LAN from sending
    "direct
       to MX" messages (spam, worms...)

    * Properly configure an A and MX record for your domain (e.g.
    mail.example.com)

    * Ensure that the public PTR record for your mailserver IP resolves with
      the same name used in MX (e.g. 192.0.2.1 -> mail.example.com)

    * Configure the mailserver to use its FQDN name for HELO/EHLO, this
    means
       that is should present itself as mail.example.com and NOT
    mail.example.local
       or something like that

    * Configure mailboxes/aliases for abuse@example.com and
    postmaster@example.com
       and ensure that someone will get and READ emails sent to those
    addresses;
       many DNSBLs will send there an email about spam/problems BEFORE
       listing your IP, and if you'll answer and fix the issue in a timely
    fashion you
       won't even get listed

    * If possible, publish an SPF record; in general a "v=spf1 mx -all"
    could fit

    * Ensure that your mailserver isn't an openrelay, there are a number of
    online
       tests, for example http://www.abuse.net/relay.html - to fix the issue
    in exchange
    , check  http://support.microsoft.com/kb/324958 and
    http://support.microsoft.com/kb/895853

    * Enable recipient verification and tarpitting
    http://support.microsoft.com/kb/842851
       so that emails sent to non-existing recipients will be immediately
    rejected during
       the SMTP session and won't generate bounces... which in most cases
    will go out
       to non-existing or spoofed addresses (and cause your server to get
    blacklisted)

    * If you're using an antivirus to check your emails, ensure that the AV
    is NOT
       configured to send out messages like "your email has been rejected
    since it's
       infected by..." the reason is the same as the above one; keep in mind
    that those
       are bounces and are bad (see http://www.dontbouncespam.org/)

    * Never send "out of office" messages to recipients sitting outside your
    organization
       otherwise, a mailbox with an active OOF may get bombed by spammers
    and your
       mailserver will start sending out OOF to spoofed addresses.... and
    get blacklisted

    * Use good spamfilters, remember that, if you ACCEPT a message you
    shouldn't
       generate an NDR at a later time, so ensure to reject SPAM during the
    SMTP session
       and to avoid generating NDRs for spam slipping through

    to my opinion, if you have got chance to change your ip address change it.

    Please, explain how this will be a solution; changing the IP will temporarily
    fix the issue until the new IP won't get blacklisted and over and over again
    and sincerely I don't think this is a solution nor a good idea

  • Hi,

    I found an article explaining how to remove the IP from spam blacklist here. Have a look.Here is the link.

    http://www.rackaid.com/resources/gmail-blacklist-removal/

    There are also some websites which lists the spam website blacklists.
    Monday, June 20, 2011 6:14 AM
  • The linked doc explains how to get out of the "google blacklist" but sincerely, given the fact that we have no idea about the blacklists the IP is in, I don't think it will be a solution... nor a "generic" one, again, each BL has its own removal process and while the linked article explains that BEFORE asking for removal you'll have to fix the REASON which lead to the listing, I won't suggest it as a "general solution"

  • 1- Check known blacklists to find if your IP address is blacklisted using blacklist check tool

    "google for adminkit blacklist check"

    2- If your IP address found blacklisted then click "removal URL" and follow instruction to remove IP address from blacklist database
