Debugging CFMAIL attribute / bad address errors

Question

We sent out email blasts by querying the database for a list of addresses and have been getting two errors which seems to kill off the loop we use to call CFMAIL:
"Error","mailWorker-5","11/01/12","10:15:29",,"javax.mail.SendFailedException: Invalid Addresses;   nested exception is:
com.sun.mail.smtp.SMTPAddressFailedException: 501 5.5.4 Invalid Address "
and
"Error","ajp-bio-8012-exec-251","10/29/12","10:16:31",,"Attribute validation error for tag CFMAIL."
I suspect that both are related to some type of malformed email addresses, but how would i determine which email address? is there a way to determine which attribute caused an error?

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>
