Hello. I've been trying to get Zimbra working for days now. I presently have it installed. But no emails in, no emails out. I've focused on DNS, split DNS, and DNSMasq. Then I started looking into the specific ports used for both the transmission and reception of emails. Then I tried to reload postfix, and the Zimbra server gave me an error telling me that postfix is not even installed. I listed the installed applications, sure enough, no postfix. Am I missing something? Shouldn't it have installed when Zimbra was installed? Zimbra 8.0.5 is installed on Ubuntu 12.04. Thanks in advance.
