    Unable to receive mail.

    Hi all,

    postfix can send mail but fails to receive mail.

    fixed ip address
    hostname - ser01.mydomain.com
    On router - ports 25/443/995/80/8080/etc. pointing to 192.168.0.218 (local ip of the server)

    I was following;
    Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 11.10)
    http://www.howtoforge.com/virtual-us...l-ubuntu-11.10

    building this server on ubuntu-10.04 (LTS)


    1)
    sent 1st mail to server on yahoo mail.
    sales@mydomain.com

    do you have mx records (primary and secondary) configured in dns for your domain?

    Whether you meant on resolv.conf? Bind9 is not installed on the server.

    The server is running on a VM of Oracle VirtualBox

    Server
    $ cat /etc/resolv.conf
    Code:
    nameserver xxx.xxx.xxx.xxx (ISP dns)
    nameserver 192.168.0.1
    on host
    $ cat /etc/resolv.conf

    what does "dig mydomain.com mx" say? it can take up to 48 hours for changes at your domain register to propagate.

    Re: Unable to receive mail.

    so lets back up a little

    - you have one static IP from your ISP?
    - you have registered your domain name with a registrar and have DNS management capability?
    - you have assigned your static IP to your router?
    - your router is also you dhcp server and dns server (forwards dns request to your ISP)?
    - you have 2(?) servers NAT'd behind your router: one physical and one virtual, both in 192.168.0.x (the vbox server is not NAT'd by the physical server, you are using a bridged interface)?
    - you have updated the DNS config at your registrar and waited ~48 hours for the changes to propagate?

    I think your resolv.conf should be identical on all systems behind your router.
    This line concerns me:

    Where is mail.mydomain.com coming from? Was that an old entry in DNS that hasn't updated yet?

    Does 'nslookup ser01.mydomain.com' give your static IP on ALL systems, and does 'nslookup <static IP>' give ser01.mydomain.com on ALL systems?

    One host (desktop) for running VirtualBox and one VM, the server
    Both bridged interface
    Both in 192.168.0.x

    - you have updated the DNS config at your registrar and waited ~48 hours for the changes to propagate?
    No. About 3 hrs after the changes.

    I think your resolv.conf should be identical on all systems behind your router.
    They are almost the same.

    Re: Unable to receive mail.

    why mydestination = localhost.$mydomain.com, localhost, mail.mydomain.com? mail.mydomain.com is not a host on your network is it?

    see http://www.postfix.org/postconf.5.html.

    make sure resolv.conf is the same - nslookup/dig must be working before you can send mail.

    make sure the network on the VM is working - is the default route correct? can you ping the router and or hosts on the internet?

    and also, don't expect anything to work until dig/nslookup shows the hostnames/IP's that you entered at your registrar (and that can take 48 hours)
