    Default canīt send or recieve mail

    Hello, I already installed Zimbra, apparently with no errors, I can log in from any location, but the problem is that I canīt recieve mails and the destinations neither. the server is behind a router, I tried to put as DMZ without success and redirecting ports but still useless.

    Help me please!!

    What you need is a Split DNS set-up and a correct and valid /etc/hosts file - read the article.

    I'll also move this to the correct forum as it's not a Zimbra Desktop (where you've posted) issue.

    Although the Zimbra Installation instructions tell you install Zimbra on a system without a firewall, you can get Zimbra to work on a system as long as all needed ports are opened on the firewall.
    Needed Ports
    Standard Zimbra ports

    * SMTP
    o port 25/tcp
    * HTTP
    o port 80/tcp
    * POP3
    o port 110/tcp
    * IMAP
    o port 143/tcp
    * LDAP
    o port 389/tcp should probably be limited by a firewall to your local network only
    * HTTPS
    o port 443/tcp
    * SMTPS
    o port 465/tcp
    * IMAPS
    o port 993/tcp
    * POP3S
    o port 995/tcp
    * Admin Interface
    o port 7071/tcp should probably be limited by a firewall to your local network only
    * LMTP
    o port 7025/tcp should probably be limited by a firewall to your local network only

    Yes, you can do that but this installation is behind a NAT router.

    Would this person not want to be sure and open those needed ports on the firewall device ?

    I open those ports on mine. Yes, I do the split DNS. Yes, I run zimbra behind a NATed router/firewall. Am I wrong ?

    I hope the original poster updates us on the progress

    Of course you need to forward the correct ports (he has mentioned that the ports are 'redirected') to the Zimbra server but the o/op can't send email either and the likelihood is that he doesn't have a Split DNS configured.

    ahh yes. The devil is in the details.
    That split DNS thing is needed.
    Anyhow, I posted all the ports to let them be sure of all ports needed.
    Most ppl know of 24 110 80 443 and myabe not some of the others.
    I wonder if that was the issue ?

    merci

    I'm confused. I have a Zimbra server behind a NAT router and forward only these ports to get things done:
    SMPT: 25
    HTTPS: 443
    Zimbra Out: 587 (not sure why I did this)
    XMPP: 5222-5223

    No split DNS. DNS is set with the CP from my registrar.
    I can use IMAP,IM, CalDAV, CardDAV, webinterface, etc...

    All admin settings are done from the LAN or through VPN.

    The situation started by me posting all the ports needed for Zimbra, depending on your firewall situation (inbound and outbound firewall). I just wanted the person with the issue to know of all the ports. The idea was to give them a list so they can verify that their port situation was not causing a problem.

    Phoneix responded by reminding me that the original poster did say they redirected the necessary ports. At that time, my post was not valid anymore.

    So, I've learned a few things from Phoenix and found that I, in may case, I only need 25 and 443. This is because I run an inbound firewall only. I only use the webclient of my Zimbra. I don't pop and imap and all that.

    So, I think all is well folks
