Unknown Sender

Hello,
we are using Merak Mail Server on a Windows 2000 Server system. We use
almost all wellknown clients on the market (express, eudora, incredimail
etc.). Here is the problem: when sending an email inside our LAN with Outlook
2003, the email arrives, but the field "FROM" shows UNKNOWN SENDER. When
sending outside the LAN everything is ok with all clients (outlook 2003
included), when sending emails inside LAN with all clients except outlook
2003, everything is ok. I suppose the problem is in outlook 2003. Anyone can
Help?
Thank you.
Colonelu
