I think you need to look at mydestination and perhaps
recipient_delimiter if indeed it's set to "-" you could be causing
unknown local-part errors too.
local_recipient_maps is just to allow you to reject incoming mail at the
RCPT TO: stage of the SMTP conversation instead of waiting until the end
of the DATA command (thus saving bandwidth on dictionary attack attempts
to spam your users).
