Forum Google Applications and vBulletin

[محروم.كوم]

Hiya

Could someone please guide me if I can set up my forum domain email to be used with google applications but rest of the things staying as they are?

www.domain.com ---- Forum Address

mail.domain.com ---- Google Applications Email

And if so then would I still be able to send mass email to users and members would still be getting instant notifications etc?

Thanks a lot
