Please help me out with SMTP if possible...

[uplinked]

Hi

I have a Google Apps account linked to one of my subdomains here (http://icvaluation.uplinked.x10hosting.com).

My Google Apps domain is http://icvaluation.co.cc

Please help me with the mailing function, how can I change the smtp in php.ini (I guess)? And is it enough to have the mail() in php or MUST I have php mailer integrated?

How can I change the incoming and outgoing mailserver to http://mail.google.com/a/icvaluation.co.cc instead of mail.icvaluation.co.cc? Who can help me with this?
