OK, so can anyone suggest the best solution for forcing FQDN in the SMTP from address?

Its a standard anti-spam technique, so any tool of that type should be able to do it. I believe that GFI Mail Essentials can do that test, as can ORF from Vamsoft. <br />

Good morning:<br />
<br />
We are currently running an Exchange 2003 server and I wanted to force messages created by some of our automated tools to use the FQDN or fail. &nbsp;For example, you can telnet on port 25 and send a message as follows:<br />
<br />
telnet ... 25<br />
ehlo<br />
250 OK<br />
mail from:rscholl<br />
250 2.1.0 rscholl@metratech.com....S<wbr />ender OK<br />
rcpt to:rscholl<br />
250 2.1.5 rscholl@metratech.com<br />
data<br />
354 Please start mail input.<br />
subject:&lt;test&gt;<br />
all bad, sender was not FQ<br />
.<br />
250 Mail queued for delivery.<br />
quit<br />
221 Closing connection. Good bye.<br />
<br />
The question is: &nbsp;Does enabling the reverse DNS resolve the issue? &nbsp;Is there a more elegant method? &nbsp;What else is affected in the process?<br />
<br />
Thanks in advance,<br />
