you are much better off rejecting those even before seing the DATA, if  
that address is in the envelope sender, or after, if it is only in the  
From: message header. No need to accept them, so no need for dovecot  
to even see them.
So this is an issue you should take, if necessary, to the mailing list  
of your MTA of choice.
