As I stated in my original post, it's version-dependant. A quick glance 
at the documentation suggests the behaviour changed some time between 
6.2 and 6.3.

PIX SMTP fixup implements RFC821 only - RFC821 is obsolete. All 
MTAs/MUAs *should* gracefuly fallback to RFC821-only support, but not 
all do - so you get problems and mail doesn't get delivered. (In a way, 
this is a good thing because a strict RFC821-only implementation can't 
do 8BITMIME and other stuff that's generally accepted as the norm these 
days. If mail doesn't flow at all, someone will investigate and get it 
fixed PDQ rather than muddling along with a crippled system)

It may not be the PIX fixup that's "broken" in that it does what it says 
it's supposed to do, but ultimately it's the one causing the problem.

I'm not losing my mind, no I'm not changing my lines,
I'm just learning new things with the passage of time
