postfix from linux Guest machine

[andlauer]

Hello,

on a Windows XP - SP2, I have installed Virtualbox 2.2.4.
then, I have configured and installed a Virtual fedora.

from this virtual fedora (linux Guest) I can connect to internet, I can ping my mail Server (Exchange), but I cannot send a E-mail

postfix in this vitual fedora is configured to forward only all mails to the exchange server (relayhost=[IP]).
- ping to the exchange --> ok
- traceroute to the exchange --> ok
- telnet to the exchange --> trying (is't ok for me)
- telnet port 25 to the exchange --> don't work (not trying and direct following error)
telnet: connect to address 10.10.1.5: Network is unreachable
telnet: Unable to connect to remote host: Network is unreachable
- telnet port 21 to a ftp server --> ok
- telnet port 25 from the windows XP to the exchange --> ok

Please help me !!!.

Regards
tom
