Mail not delivered at all

[pjmelvin]

hi,

I have done a basic setup on ubuntu 8.04 and am having a problem with mail not getting delivered.

It seems to be a DNS problem, because if i look in the queue it tells me that it has tried to connect to itself and has been refused the connection.

The address it is trying to connect to is the external addreess and the origin host/ip is 127.0.0.1/localhost.localdomain.

i assume i just need to tell the server that it is itself so the dns lookup succeeds.

Please can you tell me where to configure this.

thanks

paul

Please read the Documentation especially the Quick Start Installation Guide then read this wiki article, Do search the forusm, you'll find plenty of information telling you how to set-up DNS and how to check if it's correctly set-up.

hi Bill,

Thanks i did look at the quick config guide before and when i setup zimbra earlier this year i did do a load of DNS stuff but as this wasn't obvious from this guide i didn't bother.

I will redo the server sorting out DNS first, hopefully

thanks

hi Bill,

i followed the DNS guide but it is still not working any suggestions would be helpful.

I have included the commands i ran:

sudo vi /etc/hosts

127.0.0.1       localhost.localdomain   localhost

s

udo apt-get install bind9

sudo vi /etc/bind/named.conf.options

uncomment and change to reflect your own upstream DNS servers, i.e. remove //.

forwarders { 
212.139.132.70; 212.139.132.102; 
};

sudo vi /etc/resolv.conf

nameserver 192.168.0.200

sudo /etc/init.d/bind9 restart

sudo vi /etc/bind/named.local

zone "mydomain.co.uk"  {
                type master;
                file "/etc/bind/db.mydomain.co.uk";
        };

sudo touch /etc/bind/db.mydomain.co.uk

sudo vi /etc/bind/db.mydomain.co.uk

;
; BIND data file for mydomain.co.uk
;
$TTL    604800
@       IN      SOA     mail.mydomain.co.uk. admin.mydomain.co.uk. (
                         191108         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      mail
        IN      MX      10 mail
        IN      A       192.168.0.200
mail    IN      A       192.168.0.200

and then when i do a nslookup or dig i still get my public address

thanks

Please post

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomainname mx
dig yourdomainname any
host `hostname` <- note backticks and not single quotes

[pjmelvin]

hi Uxbod,

I have attached the outputs requested, however please note that i am trying to actually host two domains here assured-networks and melvicas and so i did all the DNS stuff for both (seperate db files etc)

Would this make any difference?

/etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.0.200 mail.mydomain.com mail

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts


/etc/resolv.conf

search mydomain.com
nameserver 192.168.0.200

paul@mail:~$ dig mydomain.com mx

host `hostname`
mail.mydomain.com has address 84.45.143.129

my external addres is x.x.x.x and i was hoping to use the mel.com as a test domain before moving the assured over

thanks paul

This is incorrect:

melvicas.com. 82253 IN A 81.86.100.253

it should point to the internal IP of your server. The hosts file is also incorrect, you need to remove the following line:

192.168.0.200 mail.assured-networks.co.uk mail

.

When you post detail on the forums please highlight each section (or command output) of code and hit the 'code' symbol - it's the # sign above the edit box - it makes the text easier to read. Take a look at the post earlier that I've edited.

hi Bill,

I need both domains to be registered to this ip, which i though shouldn't be a problem.

I am unsure hoever how to correctly configure the DNS to allow this, i simply added the melvicas.com line to the hosts file as i thought it would make no difference at all.

My primary domain is to be assured-networks but is hosted at another address, my secondary domain which is melvicas.com is correctly pointing to my external address except i haven't set up the email server yet

Please can you tell me if doubling up on all the config is correct, i.e. one for assured and one for melvicas, or not.

And point taken about the code - apologies

regards

paul

[phoenix]

Why do you need both names in the hosts file?

[pjmelvin]

hi Bill,

I am not sure that i do, and i will take out the melvicas.com then

thanks

paul
