Sending Email

[fjmd24]

I can't seem to send email from my Iphone 3GS unless I am at home on my WiFi. Even when I am out and have a good 3G or Edge signal, or am connected to another WiFi. Anyone have any ideas?

1) What service do you use (some providers, like RoadRunner via BrightHouse network don't allow using their servers except via their network WiFi's)
2) What message do yo get when trying to send mail?

More specific information about your problem will likely yield more helpful advice.
