[luau] sendmail

[karibdis]

Hey Guys,

      I got the sendmail daemon working ( just had to bind to the right 
ip. duh).  I am having one problem though.  mail sent to 
myaccount at 66.8.198.141 (my box ip) gets delivered to me just fine.  But, 
mail sent to  myaccount at MyHostMask.hawaii.rr.com  gets a failure to 
deliver message...  ( relay denied ).

      Not really a big deal, except, I was trying to subscribe to a 
couple of mailing lists, and they don't seem to be able to handle 
myaccount at 66.8.198.141.  Anybody have any ideas?

Note:  I don't own a domain of my own or anything, .com, .net etc, is 
there still something I could do?

             thanks

                                         --karibdis
