Here I beg to differ.
ISTR that one can define a custom message to follow any given return
code. By definition, a 'custom' message would not be in source.
So, questions for Nicola - have you inherited a configuration set up by
someone else? Or is this a clean install that for-sure has no such
customization? Or are you dealing with a 'far end' Exim that you can ID
as such, but have NO control over?
