    Default which ports for Zimbra behind firewall

    he there,

    i have a zimbra server in my dmz exposed to the public internet via a real address. right now i have the whole port range exposed to the box and it works fine.

    but i want to limit this to the ports i really need for zimbra.

    when i do this the messages get stock in the queue and i get a timeout connection error in the /var/log/zimbra.log

    these are the ports which i left open:
    HTTP TCP/80
    HTTPS TCP/443
    IMAP TCP/143
    PING ICMP/8
    POP3 TCP/110
    SMTP TCP/25
    SSH TCP/22 UDP/22
    DNS TCP/53 UDP/53
    PING6 IP/58
    zimbra-Admin TCP/7071
    IMAPS TCP/993
    POPS TCP/995

    am i missing one?

    thanx christof

    Default error msg?

    Does the error message mention the port in question?

    (My guess is that you also need to open the LMTP port, which defaults to 7025.)
