Now I'm testing and want to implement Mail Hosting system and I want to use Zimbra product as webmail and groupware system. But I have an external LDAP.
How can I implement zimbra to work as webmail ?
Can I install only some part of zimbra to work as webmail only?
Does zimbra has to download all mail for users to access?
Because I have and POP server to keep mail for customers already.
Thank you for your suggestion.
