[CentOS] another postfix question

hello,

i was thinking of using postfix for a mail server, the question is can i use this just for in bound email only and have my clients access this server locally. the clients would be outlook. I want this to check certain email accounts i have and download them to the postfix mail server. The reason i would think about doing this is my wife and i need to access both of these accounts and i do not want to keep them on the email account. is this feasable and secure?

thanks

Steven
