Sender rejected..

[Attila Csosz <acsosz@mail.datanet.hu>]

I send my messages directly from my linux box not through a smarthost.
So in my mail header appears a string ...@localhost.localhost in Return-Path 
or Sender header line. My messages from some address are rejected with the
following error message: 'Sender rejected' or 'Sender must exist'. 
I understand it why. With this situation my local mailing works. I tried to
resolve this situation. I force my mailer to known me as ...@mail.datanet.hu.
( I put to the defaulthost the 'mail' and to the defaultdomain the 
'datanet.hu' ). So this addresses not rejects my messages but my local mailing
not works( because I'm not really mail.datanet.hu ). How could I resolve this
situation?

Thanks 
 Attila
