Email fails to send

[Walkingthedog]

When I try to send an email on my ipad and iphone with my btinternet account it says the connection to outgoing server mail.btinternet.com failed

@Walkingthedog Can you receive an e-mail? Could be a server problem. If only the fruit problem do you have any other device working?

Have you checked your outgoing settings with what's published here?

How are the devices connected to the Internet? Using your EE broadband?

Is there any security/VPN software running on either device that might be getting in the way?

What have you put as the Outgoing Server (SMTP) settings (all of them) in your Mail app, obscuring your name?

[Walkingthedog]

I can receive emails no problem

They look fine to me not that I'm an expert. Yesterday it worked all day then failed about 7pm and still doesn’t work. 

[Walkingthedog]

Settings look correct. Sending worked OK yesterday then failed at about 7pm and still not working

@Walkingthedog With having a good yesterday in/out of e-mails, is this still device specific, do you only use apple devices for e-mail or do you have any other's that work. 

[Walkingthedog]

Ipad and iphone is all I use. Both fail.

@Walkingthedog Have you tried just sending an e-mail to yourself to see how the app/server responds. If it does not send in the sent items folder, then you will not see it.
