    Default Invitations with ZCS w/o MX records

    Hello all,

    I've been asked to install a zimbra suite that might be a little different from the standard install. For right now they send/receive email using their hosting provider, meaning they're not ready to move their MX records to the Zimbra server. They want to:

    -Send "internal" email/calendering requests using ZCS
    -Send external email/calendering requests using their hosting email (pop)

    So they would have two accounts using Zimbra desktop: their internal zimbra email and their external email by pop.

    My question is, is this something that Zimbra easily supports? More specifically:
    -What happens if they create a RDV and invite one internal collaborator and one external client? Because any accept/reject replies will be coming from different accounts, will everything be properly put into the right calendar?
    -Does Zimbra Desktop handle the sending/receiving of RDV invitations to external mail clients? Will Outlook handle an invitation request sent by Zimbra desktop?

    Thanks for any thoughts on this matter....

    You need to have valid DNS A & MX records (and hosts file) in place for Zimbra to work correctly - it's needed by Postfix for mail delivery. If you're behind a NAT router or firewall you'll need a Split DNS set-up.
