Will changing my ip address remove email blacklisting?

I found out yesterday that my IP address has been blacklisted in the RBL and as a consequence, emails sent to destinations such as China are bounced back with an error message. Local UK addresses seem to be OK.

If my understanding is correct, it is the IPO address that is blacklisted and not the Domain name  or email address. Therefor, changing my IP address should resolve the matter. Is this correct or is there an alternative solution?

The error message is :

SMTP error from remote server after RCPT command:
host mx25.dns.com.cn[119.254.72.165]:
551 212.227.17.8 is listed in RBL! ÄúµÄIP±»ÁÐÈëÖйú·´À¬»øÓʼþÁªÃ˺ÚÃûµ¥£¬Çë²ÎÔÄ£ºhttp://www.anti-spam.org.cn/Rbl/Query/Result?IP=212.227.17.8  ,Èç¹ûÄúÕýÔÚʹÓÿͻ§¶Ë£¬Çë¼ì²éÄúÊÇ·ñÕýÈ·ÉèÖÃÁËSMTPÈÏÖ¤

domain names get blacklisted too from my experience. I recommend you request to be delisted. That is the best way to resolve the blacklist.

Changing the IP address is definitely not the easiest approach. You will have to change your DNS records then (MX, PTR records) and set a new SPF record. Besides you will not get emails until your new DNS records will be replicated all around the world.

Way easier is just to send e request to delist your IP address. By the way your IP is blacklisted in several places:
Backscatterer.org       LISTED      Sorry 212.227.17.8 is blacklisted at Detail
Return codes were: 127.0.0.2      2100      281
CASA-CBL       LISTED      Mail from 212.227.17.8 refused, see Detail
Return codes were: 127.0.8.2      10800      343
CASA-CBL+       LISTED      Mail from 212.227.17.8 refused, see Detail
Return codes were: 127.0.8.6      10800      343
SORBS-SPAM       LISTED      Spam Received See: Detail
Return codes were: 127.0.0.6      3599      421
SPAMCANNIBAL       LISTED      blocked, See: Detail
Return codes were: 127.0.0.2      43200      359

Go to mxtoolbox.com click on Blacklists tab, enter your IP and follow the instructions on how to resolve the issue.

'212.227.17.8' is a 1&1 server.  You may have to change hosting to get away from that problem.

Thanks for the info so far. The other puzzling thing is that all UK emails seem to go through without problem - it is only the Chinese emails that are blocked.

That's misleading.  You will be blocked by anyone who uses that blacklist and you have no way of knowing who that would be.  I thought I saw more than one blacklist.  This http://www.mxtoolbox.com/SuperTool.aspx?action=mx%3a212.227.17.8 shows it's on 5 lists.

I have gone through one delisting process and it is a Joke! Other blacklisting companies make it so difficult and expensive.

I suspect the best solution is to :

a) Kill off the Domain
b) Change the IP Address
c) Create new Domain and email accounts
d) Maybe change Domain/Email hosting company.

or live with running my email through webmail.

Thanks
Guys

You will probably have to change hosting because it is the server IP that is blacklisted.

Hi DaveBaldwin:

I received an email from 1and1 stating emphatically that it was nothing to do with their server and the problem exists completely with my own IP address.

I tend to agree with what they say. If their server IP address was blacklisted, then anyone hosted on that server (many thousands of accounts) would also be blacklisted - it doesn't make sense that they would be exposed in this respect.

One thing that may have a bearing on why I suddenly became blacklisted on 5 blacklist company databases, was that I configured and old domain to permanently forward old emails accounts no longer used to the new one which subsequently became blacklisted.

It just gets worse!

I changed the IP address, created a new domain and email addresses less than 24 hours ago and guess what? I am blacklisted again and attempts to have some of the listings delisted is met with 'delisting not allowed'  and 'removal of IP addresses within this range from the PBL is not allowed by the netblock owner's policy'.

If changing your Ip address and domain does not work and blacklistings cannot be removed manually, where do we go from here?

There should be another reason for you to get blacklisted. Did you scan viruses/malware in your network? Check your firewall logs to make sure there is no crazy traffic going from your network outside - there are lots of viruses that can install a mail server on one of the workstations in your LAN and send spam, that will cause your external IP address to be blacklisted.

What is you external IP now?

BT changed it to 81.151.246.40

Dave BaldwinFixer of ProblemsCommented:
81.151.246.40 is not your IP but the server IP and it is blacklisted twice.

It is not exactly balacklisted, the problem is the Outbound Email Policy of BT Retail for any IP address in your IP range. You are not allowed to have your own mail server on this IP. You should contact BRITISH TELECOMMUNICATIONS and resolve this issue with them.
Besides, your DNS records are not configured properly: your PTR record resolves as host81-151-246-40.range81-151.btcentralplus.com. You have to configure proper DNS records (MX, PRT, SPF) otherwise you will be blacklisted again.

DaveBaldwin: The 81.151.246.40 address is my IP address recently changed by BT. The blacklisted address listed in RBL which is causing the problem is 212.227.126.187. This appears to be 1and1's address (SCHLUND-NET). It seems that you cannot de-list from an RBL database.

stas zed: I am not familiar with the procedure to configure proper DNS records - how is this done?

stas_zedCommented:
What is your mail server's DNS name?
To configure DNS records:
1. Contact your DNS provider and request adding MX records and  SPF record (in your case should be in format: "v=spf1 ip4:81.151.246.40 mx ~all")
2. Contact your ISP (BT) and request adding a PTR record

But before that contact BT and let them know that you want to use your own mail server.

"81.151.246.40" is also on two blacklists: http://www.mxtoolbox.com/SuperTool.aspx?action=mx%3a81.151.246.40
