The ISP who is rejecting the message needs to look at their systems to see why it has old information. It is their problem, not yours.

Hi Sambee,

Thanks for your reply, btw do we need to add any A record for this problem? Also that we found out the email are route to the Old Server in our Client Side and its been filter by their IMSS Server.

Weird thing is when we do nslookup their MX Record are using ours but their Website A Record are host in other agency.

Do our ISP need to add A record in their DNS like our MX record then our IP address?

Thanks

If your email is working correctly for all other domains then it is not a DNS issue or anything to do with what you have done. It is purely a problem with the ISP who cannot deliver to your server.

You can't have an MX record without an A record. Therefore you must have an A record for everyone else to be able to email you.

I will repeat what I wrote above - this is not a problem with anything you have done. If that ISP has your old MX records in its systems then they need to fix that problem.

Of course the major issue you will have is trying to get that ISP to admit the problem is with them as the first rule with ISP support seems to be "deny everything". (The second rule being keep asking the customer questions until they mention something that you can say "we don't support that" and the call can be closed).

Simon.

Should be no need to restart the server or IIS. If you have made the change to recipient policy then it should be live immediately.

Simon.

Hi Sembee,

Its been 72 hours, and after check the nslookup mx record, its already resolved but unfortunately that everytime i sent an email from gmail or yahoo or hotmail to try out.. its always got a error reply.

This is an automatically generated Delivery Status Notification.

The NDR you have posted is of zero help, as it doesn't explain what the problem is at all.
You need to confirm whether the server is accessible from the internet or not to begin with. There are a number of sites that will do that for you. The test inbound SMTP test here is one: https://www.testexchangeconnectivity.com/

Once you know whether the SMTP traffic is working or not, and you get an error that you can work with, you can look for a resolution.
At the moment it is unclear if the problem is because the port is blocked, IIS hasn't updated itself correctly, or something else.

Simon.

Attempting to send test email message to EMAIL ADDRESS using MX MX RECORD NAME.

The test message failed to be delivered.

Additional Details

Exception Details:
Message: Mailbox unavailable. The server response was: Relaying denied to <email@address>
Type: System.Net.Mail.SmtpFailedRecipientException
Stack Trace:
at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException& exception)
at System.Net.Mail.SmtpClient.Send(MailMessage message)
at Microsoft.Exchange.Tools.ExRCA.Tests.SmtpMessageTest.PerformTestReally()

Above are what i get from the site..

by the way sembee, these is the third time we migrate our client domain to our side (new customer) we previous has successful transfer one of our previous client MX record to point to ours.. and its working fine. but for these we pointed already for more than 72 hours but still unsuccessful, do we need to added their domain in our server side? (i doubt about it) or we need to added something in our SMTP server?

Relaying denied normally means Exchange doesn't know it is responsible for email for that domain. If the domain is listed in recipient policy (and is enabled) then IIS probably hasn't been updated correctly. You could try taking the domain out and then putting it back in again. However you don't change IIS manually - Exchange must do it via changes to recipient policy.
If it continues to fail to update then it could be a corrupt IIS metabase.

Simon.

If you don't apply the policy then it will be applied at the next refresh anyway.
