What does the bounced email message say the error is?  If it gets into the list archives and you don't receive the email then maybe it's spam settings on your email client? There should be a log on the server of the message being sent out.

Subject: Question,, Troubleshooting bounced emails

 
  I'm not sure what is happening to my list lately, but 
 I'm getting a lot of bounced email messages from subscribers
 who use Yahoo.  And recently none of my emails sent from
 Yahoo would appear in my inbox.  They would arrive in the
 archives,, but that's about it.  I'm not sure how to 
 troubleshoot something I appear to have no control of.
