Now I understand why your previous email mentioned genericstable. (I
assumed you had a valid hostname.)

genericstable is probably not needed for you. Try the "masquerade as"
option. In your sendmail.cf (if it has it), have:
DMyourdomainname

Or in sendmail.mc:

 MASQUERADE_AS(yourdomainname)dnl
 FEATURE(`allmasquerade')dnl
 FEATURE(`masquerade_envelope')dnl

This is widely documented; look at some of these:
