Subject: NDR New exchange install

I have been running a fresh exchange install for 2 weeks. The users were able to send
and recieve mail fine. Now they get a NDR instanly after they send any email. Would it be, because the
domain they are sending it to is block by the ISP? I just turned on message
filtering in the default smtp virtual server. I checked Apply sender filter,
recipient filter, sender ID filter, and intelligent message filter. Do you
think this will help? I also changed the diagnostics logging for SMTP
protocol, queuing engine, and connection manager to maximum all the rest are
medium. Where are these logs?

Here is the errors.

Description:
This is an SMTP protocol log for virtual server ID 1, connection #152. The
client at "66.36.241.109" sent a "rcpt" command, and the SMTP server
responded with "550 5.7.1 Unable to relay for
Not.abuse.see.www.DNSreport.com.from.IP.67.164.67.45@DNSreport.com ". The
full command sent was "rcpt

This will probably cause the connection to fail.

You need to look at your SMTP Virtual Server. It is denying your users from sending mail. How do they connect to Exchange? POP? Natively?

What do i look for in the virual server?
They are using a local profile connected to the exchange mail box. they are not connected to a pop account.

look at the return message, don't allow relaying on your Exchange. Most mail services check to see if your mail server is an open relay. If it is, it gets reported and the mail server will deny mail. uncheck the box allow relaying except.

Outlook connecting to Exchange server natively does not relay.

I have the default settings
where is the setting for uncheck the box allow relaying except
Did you mean The Allow all computers which successfully authenticate to relay?

Right-click the virtual SMTP server where you want to prevent mail relay, and then click Properties.
d. Click the Access tab, and then click Relay.
e. By default, open relay is blocked. The default settings are as follows: ? The Only the list below check box is selected.
? The Allow all computers which successfully authenticate to relay, regardless of the list above check box is selected.

the return admin message code 7004 indicates relaying or that the domain name the mail is from is not the same domain name as the mail server sending the mail.
