exchange

My question is that my company is thinking of providing a free email account for each of its customers. As a new company we will assume that our corporate email system will be MS Exchange server which will support about 1000 employees.

They are asking why not adding the customer list to be a part of Exchange users. My suggestion was to separate the two systems, for the corporate we can use Exchange but for customers (around 30000) we have to use a Linux based system. My only argument was that Linux can be used for enterprise services like this and Microsoft may fail.

What do you suggest?

And if you are with me on choosing Linux as the server platform, what do you suggest to use as an alternative for Exchange in Linux?

Thank you.
