-T forward should not be including the original message's From: header, only  
the one given by the -A option should be included in the autoresponse.

And what exactly is USERNAME at this point? It is not one of the variables  
that's set by maildrop. Have you actually looked at the formatted message,  
and verified that it has two distinct From: headers, instead of one with  
multiple addresses? It's likely that your USERNAME contains something that  
looks like multiple E-mail addresses.

Furthermore, hopefully, that $5 is sanitized for shell quotes and meta  
characters, at this point. If it's not, and it gets set to something from  
the original message, then hopefully it's not possible for someone to send  
you a specially crafted message that results in $5 getting manipulated to  
contain

'; rm -rf $HOME;

which would result in lots of fun, and hillarity.
