We currently have a qmail POP3/IMAP/SMTP email server serving all our employees which we are happy with. We would like to add webmail feature to a few users.
- Is Zimbra a good choice?
- Would it work with the email server residing on another server or does it need to be on the same server?
- Would we need to move to Postfix?
- And how do the user licenses work in such a setup?
