Double-Bounce

[Robert Wolfe (Ubuntu)]

Hi all!  I am getting messages in my logs where postfix is doing its 
double-bounce email thing.  I am trying to send email to an email server 
sitting behind my mail filter appliance (eFA) which routes emails to my 
main mail server on my network after scanning inbound messages.

It seems messages get through to one of the users on my mail server, 
just not to me, which generates the double-bounce@ email which is 
totally annoying.
