To make it easier for our end users, I'd like to create a frontend for our users. They will use a single hostname for web, imap and pop3 (and if possible smtp). This way they will have an easy to remember address.
I know Zimbra Proxy is for this purpose, creating a frontend to multiple backend servers. However, in my case, we have multiple standalone servers, thus multiple primary ldaps. As far as I know, Zimbra proxy will query only a single LDAP server. Thus for our needs we cannot use it.
Is there any alternatives? Any suggestion is appreciated.
