Hi guys,

I have exchange 2007 on server 2003
I can send/receive emails but when I do a dnscheck, it gives me this result

 Domain www.com.sg has only one mail-server  
  Checking mail server (PRI=30) www.com.sg [116.12.179.37]  
  Mail server www.com.sg[IP address] answers on port 25  
  <<< 220 webmail.www.com.sg Microsoft ESMTP MAIL Service ready at Mon, 16 Jun 2008 12:56:59 +0800
  >>> HELO www.checkdns.net 
  <<< 250 webmail.www.com.sg Hello [195.60.98.252]
  >>> MAIL FROM: <dnscheck@uniplace.com>
  <<< 250 2.1.0 Sender OK
  >>> RCPT TO: <postmaster@www.com.sg>
  <<< 550 5.1.1 User unknown
  >>> RCPT TO: <root@www.com.sg>
  <<< 550 5.1.1 User unknown
  >>> RCPT TO: <info@www.com.sg>
  <<< 550 5.1.1 User unknown
  >>> RCPT TO: <webmaster@www.com.sg>
  <<< 550 5.1.1 User unknown
  Probably mail server does not accept mail for www.com.sg (received status 550)  
  Some of your MX do not work properly

Yes, that is the whole problem.

It is testing "common" email addresses - if you don't have any of them (and to be honest, the only one you should have is postmaster) then there is nothing to worry about.

It is as if I said, "I tried to email sadhaksuyd8as7d89u2@yourdomain.com and it bounced" - the question is, would you care?  'cause you shouldn't.
