I found this old thread suggesting that postfix doesn't allow null
local-part addresses but it doesn't say which version this policy went
into effect:
http://archives.neohapsis.com/archives/postfix/2006-08/0445.html
I'm using postfix 2.4.5 and experiencing this problem. From what I can
tell this version was released in 2007 but the thread dates back to
2006. I'd just like to confirm that this is a version affected and not a
configuration issue before I run out and upgrade.
