My two cents... "Message SHOULD have blah blah blah" is quite different 
from "Message MUST have blah blah blah"... and SHOULD not be an error.

I think the guys at tiscali.co.uk don't respect the standard, perhaps in 
a temptative to reduce spamming. Perhaps they saw that ms-outlock always 
sends a "Date:" field, and so everyone has to do so... in spite of the 
philosophy of "be conservative when transmitting, and be liberal when 
receiving".
