Cfmail not working properly, Log files not updating

Question

I'm still trying to get this CFmail problem corrected.  The problem is CFmail is only send the mail out sporadically.  In many cases it will send out the mail and still put the message in the undeliverable folder.  My smtp server shows that the connection was opened and closed.
I'm pretty sure that I'm dealing with a CF problem  since the mail logs are screwing up as well.  In the past when I'd have  a problem with CFmail I could go to my mail.log and see what was  happening.
Those logs looked like this:
"Error","scheduler-2","05/28/09","11:00:43",,"Invalid Addresses;    nested exception is:      javax.mail.SendFailedException: 550 No such  user (website_notification) Cached lookup "
"Error","scheduler-2","05/28/09","11:00:43",,"Invalid Addresses;    nested exception is:      javax.mail.SendFailedException: 550 No such  user (wayneseattle) -ERR [email protected] not found "
"Error","scheduler-2","05/28/09","11:00:43",,"Invalid Addresses;    nested exception is:      javax.mail.SendFailedException: 550 No such  user (ca-sl-broardmoor) Cached lookup "
Now my logs look like this:
"Error","scheduler-2","12/07/09","10:05:36",,""
"Error","scheduler-4","12/07/09","10:17:22",,""
"Error","scheduler-0","12/07/09","10:33:37",,""
"Error","scheduler-0","12/07/09","10:53:53",,""
Where did the error messages go?  
Could this be a SMTP response message formating issue?  Any ideas in how  to figure this one out would be very much appreciated.

Which version of CF are you using? You may have already checked this but under "Server Settings -> Mail -> Mail Logging Settings" there's an option box for "Log all mail messages sent                      by ColdFusion". If you have it unchecked you may not see all of that data.
