Tiscali outgoing email not working

[CJClarke]

For the last 24 hours my xxxxxx@tiscali.co.uk won’t send emails. I get the error message ‘Cannot Send Mail the sender address was invalid’. This is the same on all devices (Apple iOS and OS).

Hi Notatalktalkfan1, please start a new topic and provide as much information as possible. Have you been testing in webmail at https://apps.talktalk.co.uk/appsuite.

Hi, I have been a tiscali user for several years but have encountered the same problem just in the last couple of days. I am still receiving e mails but cannot send them and I am getting the same messsage. Did you manage to resolve your issue, and if so, how?

I don't see any problem with the mail servers.

Let me know what happens with webmail sending using a browser and if you get a TT error code on sending. e.g. TT420 for example.
