Martin, Derek,

I did suspect that maybe there was a problem with the forward I use in
the spam and high scoring spam actions. I simply used my e-mail address,
rgreen at trayerproducts.com. I just did a test by setting the actions to
deliver and the bounce problem went away. I just set the action to
forward again and this time I modified my e-mail address to be
rgreen at mail4.trayerproducts.com and it's working okay now. Here are my
logs (below message), and they do show that it is a postfix problem. Any
ideas on what I might have configured incorrectly?

Thanks for your help,
Rod
