[Gllug] open relays

[will]

Hi All,

We have a customer whos server can't send to AOL because AOL have tested 
their server and found to be an open relay.  Poprelayd was installed 
last November and it seems to be working, you can only send through the 
server after popping a pop account.  However you do seem to be able to 
send if you format the destination email address:

rcpt to: CloseYourOpenRelay%aol.com@<hostname or IP of server>

this gets accepted for delivery and the maillogs show that it the mailer 
does attempt to deliver to AOL.  It is strange because it only seems to 
work for aol.com, doing:

rcpt to: CloseYourOpenRelay%<some other hostname>@<hostname or IP of server>

gives a relaying denied message.  Does anyone have any idea as to why 
this is happening and what can be done to fix it?  They are running 
sendmail 8.11.6

Will.
