[ale] New mail server for ~2500 people

[Lightner, Jeff]

What would people recommend for this given we'll be using RHEL7 or CentOS7 most likely.

I'm thinking
Postfix
Dovecot
Spamassassain


1)       Anything else I should install?   Server will only be used for email.

2)      We'll probably want to use existing active directory accounts for authentication.   Any insight on how to incorporate that into a mail server would be appreciated.

3)      Any ideas on how much space should be provided for that number of users (general of course - I don't know specifically what they'll have)?

4)      Any ideas on automatic purging of old emails from the server?

5)      They want to use a windows based client (likely Outlook and not my choice).   Are there any gotchas in using Outlook for a Linux email server? Other suggestions for clients on Windows for non-technical users?

6)      Anything else you think I should be considering but didn't ask?
