I've been taught to end business letters with "Yours faithfully" but I can see from my daily correspondence that "Best regards" is more commonly used but seems more informal.
What term should be used and under what circumstances when writing email these days?
NOTE: If other terms exist too (for colloquial use or extreme formalism) I'd like to know that too.

When working in England, I've found that "Regards" is most common, even amongst parties that have a good relationship.
When working in Australia, "Best regards" is much more commonly used. Using simply "Regards" would seem quite standoffish.
I'm not sure which is most applicable in Denmark.
