I have a primary google apps for domains account which I use for my personal email, calender, docs etc and is great.
I also receive my pop3 company email via settings->Get mail from other accounts in my account.
Due to spam I want to make use of gmail servers for my company email and have two options:
 Add my second domain as a domain alias  Create a new apps for domains account
If I do  above do I access (send and receive) my company email as if it was a separate account or is it merged into my primary domain. I want the two seperated.
If I perform  can I share my contacts / calender between the two?
I also have Act! contact manager which syncs to my primary domain and it is getting messy now with personal and work contacts being changed / sync'd to my Act CM software. I want to try and separate my personal and work contacts (but make the work them avaiable in my primary domain).
Hope this makes sense!
