We are running exchange 2003.  On the exchange logs there are NDR error that says: A non-delivery report with a status code of 5.4.0 was generated for recipient. Xxxxxxx

Causes: This message indicates a DNS problem or an IP address configuration problem  
Solution: Check the DNS using nslookup or dnsq. Verify the IP address is in IPv4 literal format.

And everytime someone send us an email it will bounce back and say:
The following recipient(s) could not be reached:

    The message contains a content type that is not supported
  <server1.xxxx.org  #5.6.1 smtp;554 5.6.1 Body type not supported by Remote Host>
Any ideas?

1. Did you check your DNS-configuration with regards to the 5.4.0?
 - Are you MX-records okay?
 - are queries for your domain resolved correctly?

2. It seems that your mailserver isn't accepting messages in a certain format. I've seen this happening when sending out emails to others (mostly with regards to 8Bit Mime). Exchange 2003 does support that, so check that you didn't disable it in the past: http://support.microsoft.com/?id=262168

Grts,

Michael

Yes, the mx records are okay.  I will have to turn off the 8bit Mime but need to do a backup first. I will try it tonight.

How do I fix a open relay? It looks like my server received spam every minute. I check all the setting and it doesn't look like an open relay.

There's a difference between being an open relay and getting a lot of spam.

The latter case you'll have to install a anti-spam filter (of any kind).
If you're an open relay, that actually means that everyone can use your server to send mails out into the world. Ofcourse this is something you DON'T want, because spammers will likely use your server to send spam and you'll get blacklisted in no time.

Usually this happens when there is NO form of "filtering" or "authentication" on the sending end. This means that your server accepts relay-requests from just about anybody. In Exchange 2003 you can set the relay settings on the SMTP-virtual server so that you can lock down your server (which it should be by default).

Yes, I figured out what's wrong with the email server. It looks like one of the computer in our network got infected with virus and it kept sending out spam so what I did was I block all of the computers on the network and in the default SMTP I uncheck where it says " All except the list below and "All computers which succesfully authenticated to relay, regardless of the list". Both of it was check before, so now I check where it says " Only the list below".  I only listed the third party IP address who host our spam filter on it and now it looks fine. No spam emails are coming through. I don't know if i did it right but looks like it's working fine now. The only strange thing is I scan all of the computers and I didn't find any virus on any of it. I used AVG to do it.
