Email not arriving to Tiscali addresses

Some emails are not making it through to either my or my wife's Tiscali addresses. One sender sent to both addresses earlier today, and messages not received in either box. Sender sent a test message to my Hotmail address and it was OK. I sent a test message from my Hotmail to my Tiscali. It has not arrived after several hours. I have sent a test message from my Hotmail to my TalkTalk address, it has arrived OK.

I have tried a test from my TalkTalk to my Tiscali and that arrived OK.

Something is not right out there.

I have now sent test messages from my GMail account to each of my Tiscali & TalkTalk accounts. Arrived at TalkTalk, not at Tiscali.

I can now further report that my test message to Tiscali from Gmail has produced a non-delivery report as follows:



Delivery incomplete
There was a temporary problem while delivering your message to username@tiscali.co.uk. Gmail will retry for 47 more hours. You'll be notified if the delivery fails permanently.

The response was:
The MX host does not match any MX allowed by the STS policy. For more information, go to https://support.google.com/a/answer/9261504


Just have to hope someone at TalkTalk is paying attention.

I spent an hour on TalkTalk Chat this morning explaining this issue, and was allocated a Case reference No. REP-14957425.

I included the non-delivery report from Bruce.

I can now report that the test message which I sent from my Hotmail address to my Tiscali address has now produced a non-delivery report similar to that reported by @Bruce-WH 

Delivery has failed to these recipients or groups:
username@tiscali.co.uk (username@tiscali.co.uk)
Your message wasn't delivered. Despite repeated attempts to deliver your message, a connection to the remote server couldn't be made.
Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that your email system is unable to connecto their email system. 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.

Many thanks Bruce for getting the delivery failure report. I am sure it will help the TalkTalk experts figure out what is wrong. Shame that the Community team won't be here until Monday to look at it. You should edit your post to remove your exact email address.

I wonder whether Hotmail will send me a delivery failure report, or what Gmail will do with the test message I sent that way. Some respondents have been saying that there is a known issue with Gmail, but as I recall that known issue was that emails from TalkTalk domains were being treated by Gmail as junk, and recipients had to whitelist the senders. Today's problem is that email TO Tiscali addresses is getting stuck, both from Hotmail (outlook.com) and Gmail.

Further to my previous post on this topic :
I find that emails sent from hotmail accounts are also not being received, like jbuchanangb reported above.
A gmail user who tried to send me an email yesterday evening has now received a message saying 'There was a temporary problem delivering your email to xxx@tiscali.co.uk. Gmail will retry for 47 more hours. You'll be notified if the delivery fails permanently'.

Plus... 'The MX host does not match any MX allowed by the STS policy. For more information, go to https://support.google.com/a/answer/9261504'


The Hotmail user received these messages :

I am having the same or a similar problem with our tiscali email addresses, using  TalkTalk Webmail. It appears that since about 10.30 am yesterday (7 Nov) we have not received any emails from Gmail users, but have been receiving emails ok from non-Gmail users.  Sending emails is working ok, to all email users.
