I have tried to send emails this morning and they won't send. I get this error message.

Message could not be sent to the following recipients: ] (550 - 550 5.1.0 AqylmO9VwpEhg Sender Domain Invalid (TT420)

 

Can anyone help?

Just to say that this transient email fault is fixed so I would expect you to be back in action.

 

Were you just using TalkTalk Mail webmail via an Internet browser and the Mail sign in?

Hi Sunshine6 

 

Looks like there's a DNS fail for the tiscali domain servers. The incident is being worked on and you can track it on the Service Status (Email) page. 

 

Have you tried webmail for all but sending to other TalkTalk Mail addresses?

 

Select here: Sign in to TalkTalk Mail

Enter your email address and password, select Sign in.

 

Are you using the recommended email client settings for TalkTalk Mail?

Upgrade your legacy mail settings
