DNS Resolution problem while receiving mail

[Murad]

Hi All,
I have the following setup :
I have one linuxbox with a static IP on the net, and one domain that is pointing onto the machine. I have configured sendmail and now here is my problem:

When I try to send an email to username@ip_address it works,
but when I try to send email to username@domain.ch I get the following failed mail reply :

Failed address: mipam@moudry.ch

--- Session Transcript ---
MX-record resolution of [domain.ch] in progress (DNS Server: 212.254.233.15)...
Name server has no records of the requested type for that domain.
Attempting SMTP connection to [domain.ch: 25]
A-record resolution of [domain.ch] in progress (DNS Server: 212.254.233.15)...
Name server has no records of the requested type for that domain.
This message is 4 days old; it has 0 days left to get delivered
--- End Transcript ---


I tried then to send email to username@

http://www.domain.ch

and it worked fine again.

Please anybody help me.

 

Also, here is the source of an email message that was sent from the box :

Helloo World

Do you have an &quot;MX&quot; record on the server that holds your DNS records? You need to create a dns &quot;A&quot; record that points mail.yourdomain.com to your IP just linke you did for your domain. Then you need to create an &quot;MX&quot; record saying that mail.yourdomain.com handles mail for yourdomain.com. This is done a little differently depending on your registrar or dns service.

1. Checkout the name resolution order on your server (/etc/nsswitch.conf file)
2. U must hav a MX record on a public DNS in order to send mail out to public network. - Hemant
