[Pkg-exim4-users] "relay not permitted" for host specified in /etc/mailname

[Ken R. Dye]

Debian, exim 4.50, trivial smarthost config.  When /etc/mailname
is updated, the update-exim4.conf is run and exim4 restarted,
I still got "relay not permitted" when exim4 would not receive
mail to itself!

Is there some reason this is not the behavior by default?  I figured 
out that I had to  dc_other_hostnames='DEBCONFvisiblenameDEBCONF:...'
but that seemd a tad wierd to me...and I swear that this used to
work before...

(my /etc/mailname is usually something like
adsl-76-223-44-207.dsl.chcgil.sbcglobal.net... I use this for "throw away"
"give us your email address" addresses that will be short-lived.
