Question

mail bounce error message - The account or domain may not exist, they may be blacklisted, or missing the proper dns entries

Asked by: skykuhl

Greetings,

I am trying to direct mail to an exchange server in our office.  I modified the dns zone and mx record and I believe it is correct.  Also tech support at my hosting company says it is correct.

I get this bounce message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

  joann@chipwebster.com
    The mail server could not deliver mail to joann@chipwebster.com.  The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.


I have tried to look at each part of this message.  I checked the blacklist on the server firewall (whm/cpanel server where the dns zone for the domain resides).  I have looked at the dns zone for the domain.

I am not sure what else to do.

Any suggestions are greatly appreciated.

Thank you

Sky

Sky,

The domain chipwebster.com is blacklisted...is this your domain? if so please amend your WHOIS records and start to get yourself unblocked, the who is information for this domain is important because this is the way ISP will contact you

Testresult for 74.55.132.18:

This IP IS CURRENTLY LISTED in our Database.
Please note that this listing does not mean you are a spammer, it means your mailsystem is either poorly configured or it is using abusive techniques.
If you don't know what BACKSCATTER or Sender Callouts are, click the links above to get clue how to stop that kind of abuse.


To track down what happened investigate your smtplogs near 16.10.2009 14:30 CEST +/-10 minutes.

You will either find that your system tried to send bounces or autoresponders to claimed but in reality faked senders, or your system tried sender verify callouts against our members near that time.

So you should look for outgoing emails that have a NULL SENDER or POSTMASTER in MAIL FROM and which got rejected at remote systems.

Read the rejection texts carefully and it shouldn't be a big deal to figure out what caused or renewed your listing.


History:

What is the problem with the whois listing?

What is the whois listing that is problematic.  The one for chipwebster.com or the one for 74.55.132.18?

The ip address is the server where the dns record for chipwebster.com resides but it is not the mail server.

thank you.

First of all if you do an MX record lookup for chipwebster.com it returns:


10      mx-173-9-104-1.chipwebster.com      0.0.0.0

chipwebster.com has no IP addresses associated to its MX record so when you send an email from the outside it wont go anywhere...

74.55.132.18 is currently blacklisted

Normally when an ISP believes email originating from a domain for example your domain has a mismatch MX or is generating SPAM they look at the whois information of the domain which int this instance is Mark Cutone and they would send him an email advising to get in touch within 48 hours to either tell them you had a mismatch MX which you have resolved etc

Whats throwing me off track is.....I can telnet to chipwebster.com on SMTP port 25 from the outside which resolves to your blocked record 74.55.132.18 this is also your MX record!

74.55.132.18 is the server that the dns zone resides on.  The ip address for the mail server is 173.9.104.1.

I have set the a mail record to 173.9.104.1 and the mx record to mail.chipwebster.com.

I just did this yesterday afternoon.  If there any chance that it hasn't propegated properly?

I am looking at the mx record again and the zone.

Thank you.

Also how did you do that mx record look up?  Thanks very much.

 

by: skykuhlPosted on 2009-10-18 at 08:29:49ID: 25600170

sorry about that stupid last question.  I see you can use mxtoolbox.  

I see what you are talking about there.

 

by: skykuhlPosted on 2009-10-18 at 08:32:46ID: 25600176

There is a txt record in the zone that looks like this:

"v=spf1 a mx ip4:74.55.132.18 -all"

Should that ip be the ip address of the mail server?  Which is 173.9.104.1?

This is an exchange server in some office.  The dns zone resides on the web server.

 

by: Raheem05Posted on 2009-10-18 at 08:35:21ID: 25600188

You can do MX lookup via:

1 open a command prompt
2. type nslookup and enter
3. type set type=mx and enter
4. type the name of the domain for example chipwebster.com and return

Or you can use web based tools such as:

http://www.mxtoolbox.com/

ok how have you setup the MX record?

For example you should be creating a sub-domain called mail.chipwebster.com and setting the IP to the correct IP of your public interface of the firewall / security applicance

you then change the MX record of the domain chipwebster.com to mail.chipwebster.com and the cost i.e. 10

 

by: Raheem05Posted on 2009-10-18 at 08:38:01ID: 25600195

Sky take at my last post you should have a few free subdomains create one called mail.chipwebster.com and make sure the IP of this is the public ip of the correct firewall you want this to go to then doing your natting at firewall end then point the domain chipwebster.com for MX to mail.chipwebster.com

 

by: skykuhlPosted on 2009-10-18 at 08:40:26ID: 25600200

I am looking at Mark Cutone's mail and I don't see any messages related to this issue.

 

by: Raheem05Posted on 2009-10-18 at 08:41:52ID: 25600203

some may contact you by this method others may use a generic abuse@domain.com / postmaster@domain.com

its not unknown for no communication either...

 

by: skykuhlPosted on 2009-10-18 at 08:55:50ID: 25600262

Ok thak you.  I am looking at making a sub domain now.

 

by: skykuhlPosted on 2009-10-18 at 09:05:26ID: 25600289

So I will have to make a sub domain called mail.chipwebster.com and give it a redirection to the mail server address.

I will do this however in my browser mail.chipwebster.com already resolves correctly.  It is a win small business server and when I browse to mail.chipwebster.com/remote I can log on to the remote web workplace.

 

by: Raheem05Posted on 2009-10-18 at 09:15:36ID: 25600317

OK so someone has created mail.chipster.com for you already

Name:      mail.chipwebster.com
Address: 173.9.104.1


is 173.9.104.1 the correct IP?

If so then just change the MX record to mail.chipwebster.com and the MX cost so for example 10 and let it replicate around

 

by: Raheem05Posted on 2009-10-18 at 09:16:51ID: 25600324

you are changing chipwebster.com mx to mail.chipwebster.com mx cost 10 and it can take 24 /48 hours to take effect then do an mxlookup for chipster.com this should resolve to mail.chipster.com mx cost 10 and ip 173.9.104.1

 

by: Raheem05Posted on 2009-10-18 at 09:27:49ID: 25600358

if you are still struggling how do you change your mx records for chipwebster.com who hosts this domain and if you have a login provide screenshots and i will help you out if you have a managed service with your ISP for example tell them to change the mx record for chipwebster.com to mail.chipwebster.com at an mx cost of 10 and verifiy this should be the only mx record so when someone sends a domain to firstname.lastname@chipwebster.com it goes to 173.9.104.1 once this change has happened check tomorrow by doing an mslookup for chipwebster.com and this should resolve to mail.chipwebster.com and you just need to make sure your firewall has a rule for any SMTP connections on port 25 is natted from: 173.9.104.1 to private ip of exchange inside your network and your done
