${sg } is not clever enough to realise that the RE and substring are, in this case,
selecting a list of static strings. Therefore it cannot be used as a de-taint mechanism.

Instead, use "inlist" :-

${if inlist {$local_part_suffix} {-bounces : -confirm : -join} {$value}}

(obviously, with whatever elements in the list are needed).
The facility was described in the Newstuff file.

If the removal of a further suffix (the "(\\+.*)?" in the RE above
is needed, do that before doing the list-match.
