Freebsd list rejects mail.

[Marwan Sultan]

Hello everyone,

   I have my own pop3 email system, when i send from my private Email, it 
always rejects and says:
   cannot find my host name, I knew this is a sendmail, or whatever freebsd 
list restrictions,
   but how to solve it from my side?

   the machine has multi IPs, and when i send the email, it takes it as its 
from 216.65.57.4
   in the time that its multi IPs,

   what MX i should change?

   the ip 216.65.57.4  already resolve to something.servername...

   any hint, idea appreciate it
   thanks.

  Marwan.
