..but I chose "/" do delimit my local_part suffixes because it was OK by
the RFCs, but unlikely to be found anywhere in my department :-/
Subsequently I've needed to add the rewrite rule:
# allow "--" instead of "/" for dumb web forms that don't know RFC 2822
^(.+)\-\-(.+)@REAL_DOMAIN $1/$2@REAL_DOMAIN Tbct
..which, although ugly, Works For Me.
