you can test lookups using 'postmap -q'. /^(me)-...@example\.com$/ m...@example.com do this for all valid addresses. If you use a wildcard like /^([^-]+)-...@example\.com$/ $...@example.com you will break recipient validation and your postfix will accept mail for any doesnotexist-ran...@example.com.
