Debugging CFMAIL attribute / bad address errors

It's a shame if one error should kill off the loop. Imagine the error occurring after just 3 sent mails out of a 5000-message job! If throughput is important, then you might want to redesign as follows:

<cfloop query>

<cftry>

<cfmail>

</cfmail>

<cfcatch type="any">

<!--- handle errors, for example, log e-mail address and error message --->

</cfcatch>

</cftry>

</cfloop>

ColdFusion has an isValid() function that will tell you if the string has the correct format for an email address.  As far as I know, the only thing that will tell you if a properly formatted email address actually exists is a delivery failure notification.
