“Sender address not valid”

Suddenly I can’t send emails from apple mail app on all devices- get “sender address is not valid” , but I can send from webmail. It doesn’t even try to send...goes straight to outbox where it stays until I use a different server.  I’ve tried deleting accounts and changing password but to no avail. Spoke to BT who have no idea. Help please?

Hi.

Is there by any chance a proxy set within the app? Webmail will not have that issue.
