    Default Possible port issue.

    Hi,

    I'm running 5.0.2 with RHEL5 and I'm having some issues with ports. I'm not sure if it's a Zimbra issue or Linux issue. Mail is not being sent and recieved with the following ports open on our Sonicwall:

    80
    443
    220
    143
    389
    1433
    110
    25
    53
    138
    636
    7071
    7047
    7306 - 7307
    7780
    10024 - 10025
    22
    514

    Out of frustration on Friday I opened ports 1-9999 and email is sent and recieved just fine. I'd like to have the least amount of ports open, but am I missing something? We're only using the web client also.

    Thanks.

    I think that did it. Thanks! I must have overlooked 7025.

    I now have another issue regarding the ports. I doubt this is a Zimbra issue but more of a Sonicwall issue. I am wondering if anyone has seen this.

    My email server works fine for maybe 20 minutes or so then completely stops sending/receiving mail. If I log into my firewall and disable a port (usually 8080 is what I choose) and re-enable it the Email server is up for another 20 minutes or so.

    When I run postqueue -p when the mail server is not working all of the emails say connection timed out. Then I close and open a port and it works again.
