iPhoto 11 and email issue

[mac2thefuture]

I keep getting a sending error report when trying to email direct from iPhoto 11.
As I understand it, iPhoto pulls all address details direct from Mail so why would it falter.
For interest, Mail is working and I used via Sky mail in the UK.
Thanks

OK, i set up a gmail account to work through Mail and iPhoto now works.
Does anyone know what the default settings are for Sky? outgoing, smtp etc etc?
