Subject:	envelope sender '<>' via uucp gets rewritten as <MAILER-DAEMON@>
Group:	Postfix-users
From:	ram
Date:	9 May 2008

on my postfix 2.4.6 server when mail arrives from uucp and the envelope
sender is '<>' then the address is translated to '<MAILER-DAEMON@>'

But the domain name part is missing. I want this to be
'<MAILER-DAEMON>' not a dumb '<MAILER-DAEMON@>'

I am feeling stupid , but I cant find where I am missing the domain name
entry

Thanks
Ram
