Sending to my ntlworld email bounces with recipient's domain does not exist - [logged under F011775373]

Same here, causing me a real headache on a password I urgently need to reset.

Is there a way to log a case with this? Every time there has been some kind of email issue like this in the past and I call up, I have someone outside of the UK telling me I don't know how to use a computer and asking if they can have access to my email to prove I'm too thick to log in properly.

Same here - no ntlworld emails arrived since 9 o'clock last night (checked on Outlook, VM web client and various devices).
Getting error sending via webclient;
"(421 - 421 4.1.0 SMTP400 Cannot validate your Mailfrom Domain ntlworld.com in DNS, adjust or retry later ;id=2SYHurHTnnnnnnnnnnn;sid=2SYHnnnnnnn;mta=oxsmtp3-prd-nl1-vmo;d=20250409;t=122101[CET];ipsrc=x.x.x.x;

Same issue here. Have tried to contact on X also - please can we have some update asap

I have had the same issue this morning. After calling. I have been told that it is an outage with the NTLWORLD server and this will be resolved by 13:30 - UK time I presume. Still can't received or send emails. Fingers crossed this is sorted by 13:30

I've just received a couple of emails on my ntlworld.com accounts from external sources, so it might be working now

I have had one email in at 13:53 but when I try and send an email into my ntlworld email it does not get sent- the following message informs me that the domain does not exist (see below).

I cannot send emails from my ntlworld email address.

Has anyone got any news on when this will be fixed?

Delivery has failed to these recipients or groups:

********@ntlworld.com (*******@ntlworld.com)
Your message couldn't be delivered. The Domain Name System (DNS) reported that the recipient's domain does not exist.

Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their domain isn't properly registered at their domain registrar. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.
