As pointed out earlier in this thread, this is a qmail issue.

The SMTP MAIL FROM is set to <> on purpose:

http://tools.ietf.org/html/rfc3834#section-3.3
http://tools.ietf.org/html/rfc5230#section-5.1

This prevents other automated responders from replying to this message, 
e.g. an MTA sending a delivery failure. This (among other safeguards) 
prevents mail loops.

The above change is therefore not recommended.

Regards,

Stephan.
