Thanks for writing this up, I've been quite pissed off about it myself
for a few days now.

This page will tell me nothing either. I've tested that I receive root@
and postmaster@ mail from a yahoo address; but I've never gotten
anything in response to filling out those forms.

Just in case it helps others get mail to their families & friends, this
is the router I added to my exim.conf. I added it *before* all other
routers in the ** ROUTERS CONFIGURATION ** section...

  driver = domainlist
  transport = remote_smtp
  route_list = aol.com smtp-server.nyc.rr.com byname

(obviously, change "smtp-server.nyc.rr.com" to your own ISP's smarthost)

At that point mail started to go through to aol, but I got messages like 
this in /var/log/exim/mainlog when using that router:

2003-04-15 18:48:10 195ZDm-0004sD-00 failed to open database lock file
/var/spool/exim/db/wait-remote_smtp.lockfile: Permission denied (euid=8

to fix that I just did this:

# chown -R mail:mail /var/spool/exim/db

I hope this is of help to someone...
