exim4 authentication in etch?

["Thomas H. George" <lists@tomgeorge.info>]

I wiped the hard drive, did a clean installation of etch, configured 
exim4, put the user:password in /etc/exim4/passwd.client and tried to 
send a message.  The entry in /var/log/exim4/mainlog showed 
authentication required.  I had saved a debian users posting from Jan 
2006 explaining how to modify the exim4.conf.template adding a line 
"hosts_require_auth = outgoing.verizon.net" but the instructions don't 
match the current exim4.conf.template file.  Does anyone have a current 
instruction or reference for the needed modification?
