Environment - Non Weather Related; Procedure
During approach; controller vectored flight no more than 4 nm behind a heavy B767.  We had a 170 knot speed assignment to the FAF.  By the time preceding aircraft landed we were probably less than 3 NM from touchdown.  At approximately 100 feet AGL; encountered violent and pronounced roll due to B767s wake.  Executed an uneventful go-around and returned for a normal landing.Memphis was experiencing strong quartering tailwinds aloft until below 1;000 feet above TDZE with a slight quartering tailwind (220/5 - for RWY 36L) at the runway.  ATC did not fully account for these conditions and possibly miss-applied RECAT.  Spacing might have been OK if not for the wind conditions.  ATC needs to be a bit less aggressive with their spacing.
Captain reported encountering 'violent and pronounced roll' at 100 feet AGL from a preceding B767 wake on final to MEM. Reporter stated ATC 'needs to be a bit less aggressive with their spacing'.
