Pulling my hair out!

[fgaughan]

Please point me to right direction as i am pulling my hair out.
I am using Centos
First time i installed Zimbra i didn't set host name etc and i had a play with Zimbra.
Was impressed but obviously i couldn’t send and receive mail as I was testing it out.
So I decided to do a proper install.

I registered a domain with 1and1.co.uk lets call it needhelp.co.uk

In the control panel of 1and one I put in my fixed IP Address (A-Record)
As I have been given 2 fixed ip address from my isp service provider
Am I correct in doing that?
What do I put in my etc/hosts?


When installing zimbra it get the following
DNS ERROR - none of the MX records ineedhelp.co.uk
resolve to this host

Now I don’t understand fully about DNS and email mx ‘s

The FAQ on 1and1 does not make sense to me to find out about DNS and MX

Does 1&1 allow you to manage your DNS including setting up MX Records? If 1&1 don't allow you to set MX records then you need a DNS service that does have that facility such as dyndns.or or (I use) easydns.com

I assume you're behind a NAT router? If so your /etc/hosts file would contain:

127.0.0.1 localhost.localdomain
192.168.x.x mail.ineedhelp.co.uk mail

where 'mail' is the name of your server. There is a tutorial in the forums on DNS, have a look for 'DNS in a nutshell' it'll tell you what you need to know. You may also need a local DNS server so review the wiki on 'split-DNS' as you'll probably need to set that up.

Thanks for reply
Its all coming a bit clearer to me

Typing this at work so i wont be able to do this till i get home grr (thats how obsessed i am in getting it to work)

1and 1 does allow me to manage DNS and setting up my MX records but trouble is i don't know what to put in it.

Have a review of the DNS in a nutshell post and it should become clear what you need at 1&1.

Hi-
You don't have an MX record.

Your MX record needs to point to either:
1) your router(if you have one), the port forward your router's mta port to your natted IP
2) your machine.

Your record should have a priority of 10, unless you have more than 1 mail server.

if the machine is named "mail.ineedhelp.co.uk" and you want to have email addresses like "fgaughan@ineedhelp.co.uk", you need to see results like this:

$ host -t mx ineedhelp.co.uk
ineedhelp.co.uk mail is handled by 10 mail.ineedhelp.co.uk.

$ host mail.ineedhelp.co.uk
mail.ineedhelp.co.uk has address A.B.C.D

if the machine is on a lan with private ip addresses, you will have best luck running a nameserver locally returning the private ip address (as well as any other dns info for the domain, i.e. the mx record). the rest of the world outside the lan will get the public ip address from 1 and 1
