TCP port 7335 and

[MacTI]

I'm trying to make a list of ports that I should open or close on my Zimbra installation and I don't know what those TCP port are for : 7335 and 10015. Can I close those ports from the outside?

I believe by default ZCS is not using any port higher than 7071 (the admin port), unless you have set an https port to access your mail from outside within the range that you have specified.

Also, there's a wiki where you can find the ports used by ZCS.

Hope this helps.
