Re: Zimbra 9 - Patch 6 (Feedback from video)

Definitely something not worth paying for at the moment, IMO.

Re: Just install Zimbra

I never use dnscache either. At the very least I use dnsmasq for testing.

It was Network edition but the same can be done with FOSS. Yes, ldap replication is the key.

Re: More than one standalone installation

I've done something similar. I've had 5 or 6 standalone servers with 1 at corporate hq as master ldap and the rest at remote locations with ldap replication turned on. Worked great.

Re: No gui on browser, nothing works...

Sounds to me like you just need Dovecot and Roundcube if you're wanting something bolted on to postfix and apache. ZCS is all inclusive of these services and isn't meant to be added to anything.

Re: Block all but specific IPs

Use 587 / 465 for client submission(that's what those ports are for) and only allow incoming port 25 from spam relay.

Re: Block all but specific IPs

Sounds like a job for firewall rules instead of postfix.
