Uable to send or recieve mails

[Shikha Sood]

When I try to make an appointment, I give the basic details and add some attendees. Everything works fine. The appointment appears in the person who made the appointment. But the attendees don't get any email. When I save the appointment, I get an error:
Invite not sent, one or more addresses were not accepted. Rejected addresses: Shikha Sood <shikha.sood@hostname>

I looked up some threads some people suggest that the DNS setting should be proper.
I added
The MX records in my etc/hosts file as follows:

@ MX 5 mail.yourdomain.com

You'll also want to set up an "A" record for the "mail" host on "yourdomain.com" that points to your external IP address.

mail A 215.38.22.122

But it not makes any difference.

Also, when I try to send/receive mails, though it says "message sent" no message appears in the recipient’s inbox
Don't know whats the problem.PLease suggest

I found out that the messages are there in the store folder, but are not visible in the inbox.
I have disabled DNS lookup also, still thing are not working

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

Hi
I tried all the commands suggested by you.This is what I get when I run them:

root@test-desktop:/etc# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
172.21.108.247 FQDN test-desktop
@ MX 5 mail.test-desktop.com
mail A 172.21.18.247

# The following lines are desirable for IPv6 capable hosts

Any Idea, what I am doing wrong?

You've used the wrong commands for dig and host. Run the dig command with YOUR domain name and for the host command you were told to use backticks not single quotes. Run them again correctly.

Hi Phoenix
I ran alll the commands again as you suggested.Actually I am new to both Ubuntu and Zimbra.So might be doing something really stupid.Following is the output:

test@test-desktop:~$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost

test@test-desktop:~$ host `test-desktop`
bash: test-desktop: command not found
Usage: host [-aCdlriTwv] [-c class] [-N ndots] [-t type] [-W time]
[-R number] [-m flag] hostname [server]
-a is equivalent to -v -t ANY
-c specifies query class for non-IN data
-C compares SOA records on authoritative nameservers
-d is equivalent to -v
-l lists all hosts in a domain, using AXFR
-i IP6.INT reverse lookups
-N changes the number of dots allowed before root lookup is done
-r disables recursive processing
-R specifies number of retries for UDP packets
-s a SERVFAIL response should stop query
-t specifies the query type
-T enables TCP/IP mode
-v enables verbose output
-w specifies to wait forever for a reply
-W specifies how long to wait for a reply
-4 use IPv4 query transport only
-6 use IPv6 query transport only

Before attempting to install Zimbra I would recommend that you read :-

http://www.zimbra.com/docs/os/latest...erver_install/
Split DNS - Zimbra :: Wiki

and then read them again. Your /etc/hosts contains invalid values and you need to read up on what a FQDN is. You need to understand the basic principles first of how DNS (A,MX,CNAME) records etc work and then you can move forward
