This is a known setting : postfix uses $recipient_delimiter to match
those sort of recipient+extension at domain.tld mail addresses.
See what your setting is via 'postconf recipient_delimiter' and
set it accordingly in you main.cf file.
  It could be '-' in this case you can post to 
username-extension at example.org.

Btw, please wrap your lines length to a sensible value (72 would be nice).
