btconnect email account sending to a transferred out Domain failing

burrowsr1 — Thu, 01 Mar 2012 12:29:25 GMT

I have a client who has recently transferred out their domain away from BT and is hosted else where. All DNS is configured correctly however they cannot seem to receive email from btconnect.com accounts with the sender getting delayed warnings and NDR's

Delay message received by sender (sender@btconnect.com) below:-

From: Mail Delivery Subsystem

[mailto:MAILER-DAEMON@c2bthomr12.btconnect.com]

Sent: 29 February 2012 20:10

To: sender@btconnect.com

Subject: Warning: could not send message for past 4 hours

The original message was received at Wed, 29 Feb 2012 15:53:48 GMT from c2bthomr09.ncs.ibs-infra.bt.com [10.87.69.230]

This is driving me up the wall. No email is hitting the clients server at all so its not an AV/SPAM security issue.

I am sure it is to do with BT caching old MX records for the cliients domain.

If anybody has any ideas then please help

cheers

Hi burrowsr1

This sounds like your clients domain name has not been removed properly from the BT mail platform, I would advise contacting the helpdesk and supplying them the reports and error messages to allow them to investigate the issue further. Here is our contact options.

Hi. You might want to send test emails to other mailbox in the receiver's domain just to check if it's just a single mailbox issue.

That's if you have the privilege of the clients to agree with this. 🙂

Thanks for the replies

BT are saying the transfer out was successfull. I thought about RDNS but we are smarthosting so shouldn't be any need. I literally am stuck and its bugging me.

The client is now telling me it is not just BT Connect accounts.

Oh the joys
