Yes, sorry.

It might be possible to use an empty domain, it depends on how sonic.net is 
configured. An empty domain is usually replaced by the server's own domain, so 
the effect would be that the emails came from "root@xxxxxxxxx". This might 
work, unless sonic.net demands smtp-auth even for incoming emails when the 
domain is sonic.net. It would be cheating though.

Note that the bounces didn't have an empty domain, they had a completely 
empty address, <>. This is handled specially by email systems.

Configuring your postfix to authenticate properly with the sonic.net smtp 
system would be another way to go.
