[IMGate] New Server config

[Joel Staiman]

My company is looking to double it's size.
To that end I need to come up with general costs for this.

What is the recommended hardware config and costs for the following:

        Dedicated Postfix server for outgoing mail ( * 2)
        
        Dedicated Postfix server for anti-virus ( * 2 )

        Dedicated iMail server for 25k users.

Thanks in advance

Joel
