Four and a half years ago I looked in detail at 34 email transfer

rearrangement of fields.
Anyone who uses such software will find it difficult to diagnose problems
and will suffer from less effective spam filtering until the software is
fixed. I don't think improvements to the specification should be held back
by idiot implementations.
Did you find out how widely deployed these manglers were and whether they
were usually installed as end-points or as relays?
