Smartermail sync to Mac?

[RFH Customer: plandon]

Can anyone tell me if it's possible to set up CalDAV on a Mac running OSX Snow Leopard? If so, what are the server settings?
I'm trying to sync a Mac Pro, a PC running Win 7 (Outlook 2010) a Blackberry and an iPhone..... Google Apps will work but it's really clunky on Outlook.

Problem solved! In the end, I succeeded in syncing my Mac, XP laptop, Win7 PC, Blackberry and iPhone using Gmail contacts and calendar and Sync2 for the two machines running Outlook 2010.
