Hi there,

You can't send through btconnect servers with a btinternet email so change the smtp server back to smtp.btinternet.com and click the more settings button in your account properties.  Enable 'my outgoing server requires authentication' and keep the dot in 'use same settings as incoming server'

Thanks
