This draft allows both prefix and suffix encoding, but still requires
both user and detail part to be substrings of the local part.

Why? VERP (http://cr.yp.to/proto/verp.txt) is a popular encoding
and if you relaxed the encoding specification, Sieve could be
used to decode it.  A filter in front of a MLM may be very useful.
