       HELO.
      when i say......
      MAIL FROM:someone@some.other.domain
      ....it responds that the sender's address should resolve.....what
      does that mean???
      i thought because it sends mail ......it should accept all sender
      addresses!!!
      At the same time.....if i say
      MAIL FROM:some_other_login_on_my_linuxbox@localhost
      the mail is sent....even if "some_other_login_on_my_linuxbox" knows
      nothing about it!!! 
When you give MAIL FROM: someone(a)some.other.domain, the domain 
some.other.domain should be resolved by your local DNS or the DNS of your 
ISP. When you use some_other_login_on_my_linuxbox@localhost, sendmail knows 
that its a valid domain.
