I recently set up an email system for a small company using cPanel, hMailserver and Thunderbird. I actually looked at Zimbra but decided to go with a Windows-based solution. I also considered Google Apps, but was afraid it wouldn't allow for fine-grained control over access permissions (i.e. managers seeing subordinates' accounts and restricted shared folders) and also unrestricted creation email aliases/accounts. Should I have taken a closer look at GA? Thunderbird isn't the easiest to use, but I like how it's easy to work with shared IMAP folders.
