Thanks for your help, its all sorted now. Got to speak to a UK tech, who sorted everything out including my other providers mail account in about 10 mins.
Turns out there was an issue with the password, once re-set it all started working. My demon account is working, using an ntlworld as an outgoing server as it doesn't require authentication, will only need this until the end of the week.
