   <smohammadn@ir-sr.com>): Host or domain name not found. Name service error
   for name=phpRADmin-server.phpRADmin-server type=A: Host not found

Are you using a CNAME as MX record?

If so, set the MX record to an A record!

[Hellbound]

thanks god you replied.

I got so panic.

what happens is that this server is behind the nat and I couldn't figure out how to fix the mx record and there no email at all. so what I did was I set the dns server to godaddy and with their so call " total dns control" I set the MX record to www.ir-sr.com (just typed it there), should I type @ instead of that to make it A record?

thanks

I do not have godaddy, but this is how I have set it up.

PHP Code:

A (Host)     Points to
@            IP_OF_SERVER
mail         IP_OF_SERVER

CNAMES (Aliases)

Empty

MX (Mail Exchange)
Priority    Host    Goes to
0            @    mail.website.tld

ok,
now its totally get rejected after I applied this:

[check the attachment screenshot]

and I use this tool > www.dnsgoodies.com to check mx status
which all are empty ! dont even know why

[Hellbound]

ok,
sorry I found a mistake, but still the same.

changed the first mx record to > host2.persiasys.com

thats my server address

and deleted the second one.

but still bounced back

Your MX looks fine now:
http://www.dnsreport.com/tools/dnsre...main=ir-sr.com

Change the 0 @ is-sr.com to
0 @ mail.is-sr.com
You can remove the 10 @ www.is-sr.com

Hmmm whats the domainname that you are trying to setup?

[Hellbound]

that's www.ir-sr.com
here's two thing:

my email still get the same error.
I suspect it is because of installing phpmyradmin that I installed for radiusserver controlling

second this is that my BIND service is not running. how to fix it?

thanks

What's in /etc/hosts, and what's the output of

hostname -f

?
What's in /etc/postfix/main.cf (please strip out the comments)?
