We are on vacation and since we arrived we can not send emails? No setting have been changed. iPad and iPhone same issue and only bt internet.com with this issue?
any ideas how to fix
Use a web browser and log onto web mail instead of using an email app.
I have 8 accounts set up so this is not an option. I just want to be able to use as before all in one place
It may be that which ever network you are using is blocking your email accounts when used via an email client.
You could add all your email accounts to one of your email accounts on webmail via the account's settings and this will act in the same manner as an email client.
