[Exim] exim internal bounces????

Hi All,

I am having slight problems with exim 4.12/mailman when I send email from
a remove machine to my mailman server, it processes fine, but the return
mail appears to bounce... The question is is there any indication from
this log entry as to what is doing the bounce, it it the machine that exim
is running on, or is it further up the chain. I have tried duplicating
this with exim -v but all works with no problem
