    Default Zimbra behind PFsense firewall

    I have a pfsense firewall and a Zimbra server connected to this firewall.
    Even if I open the necessary ports, the Zimbra server does not send and receive e-mails, but if I connect it outside the firewall works perfectly.
    Can anyone tell me all the ports open on the firewall for Zimbra will work?
    Thanks

    Did you setup the needed split-dns?

    Hello, the Zimbra server works perfectly if I connect directly to one of our fiber optic Internet lines.
    However, if I connect the server to the switch and then the server goes through the firewall, no longer works.
    I tried to open the doors on the documentation that is required to open, but Zimbra, in that condition does not work.
    I have deduced that the problem is with the configuration of the firewall, but I do not know so thoroughly Zimbra to know how you must configure the firewall to ensure that Zimbra works.

    It's not about the firewall, it's about your "whole" setup.

    As you have a firewall, you're certainly using NAT.
    If you use NAT, you need split-dns (search forum and wiki, everything is in there).

    I agree with this 100%. I am also using Zimbra behind pFsense and it works 100%. BUT, go read the SPLIT DNS stuff. Without it you will not get it to work...
