Deferred Mail

[gorilly]

Hi

i have set up a test server (open source)

Its all running ok but i'm having trouble sending and receiving mail - everything ends up in the deferred queue and the origin ip is 172.0.0.1

Now im pretty sure i have my hosts file correct,
it reads (this is exactly what it reads)

172.0.0.1 localhost.localdomain localhost
192.168.0.10 mail.gorillystestdomain.co.uk mail

on my domain i have set an A record to point at my external ip of my zimbra server 90.X.X.X
then i have set an MX record.

can't see what im doing wrong!

thanks

As you are on a internal LAN have you follows this guide ? Split DNS - Zimbra :: Wiki

Also, if you are still having problems please post the following :-

cat /etc/resolv.conf
dig domain.com mx
dig domain.com ns
host `hostname` <-- note backticks

* Note: replace domain.com with your own

[gorilly]

i will have a try with BIND.

should zimbra really be in a DMZ then?

[uxbod]

should zimbra really be in a DMZ then?

that really depends on your security policy

[gorilly]

not the best idea then!

ok so i have now installed and configured bind9 and ran dig

root@mail:/home/cup# dig thepressurepoint.co.uk mx

if i run an mx lookup externally i get the ip external ip of my router / zimbra server.

25 is fwd

[uxbod]

dig is not returning anything. what do you have in your /etc/resolv.conf ? it looks like from the dig you are pointing at :-

;; SERVER: 192.168.0.20#53(192.168.0.20)

so if you have installed BIND on your Zimbra server you need to update resolv.conf to point at 192.168.0.10 instead. This should then resolve the NS and MX correctly.

[gorilly]

hi sorry server is on 20 not 10 i made a typo earlier

in resolv.conf i have

search thepressurepoint.co.uk
nameserver 192.168.0.20

[uxbod]

something is wrong in your zone files then. what does /var/log/messages show when you start up BIND ?

[gorilly]

just looked (didnt know to look there)

yes its not working correctly, i will try and fix it
