I assume that your windows box is on a private subnet that is being masq'ed by 
the linux box?  You need to tell your mail server that it's ok to allow your 
local systems to send mail.  You probably want to allow that private 
subnet(192.168.?) access. I think you want to look at /etc/mail/relay-domains.

HTH,
