I was looking over the latest requirements for M3. I have had a test server running from M1 to M3 and am getting ready to put a production server online.
The QuickStart Guide lists the following ports:
Table 1 Zimbra Port Mapping
Tomcat IMAP SSL 993
Tomcat POP SSL 995
Tomcat LMTP 7025
Questions: I need to know what ports need to be open to the Internet. Port 7071 is not listed but I know that one needs to be included if I want to administer when off my local network. What about LMTP 7025? Should this be open to the Internet as well or just the local network? Are there any other ports that need to be open?
