Hi,

I have set up an Exchange 2003 server ( on win2k3), behind an ISA server.:

ISP - (staticwanip)cisco router(10.0.0.99)-(10.0.0.203)ISAserver(192.168.0.2)- (192.168.0.1 )domain network And exchange server
only port 25 is open for incomming mail to the exchange server.

Problem:
The exchange server can send mail to all domains: @hotmail.com / @gmail.com / @skynet.be / ...
And he can recieve the mails from all domains but...
But It can't recieve mails from hotmail.

I see hotmail.com connecting in SMTP sessions for 600 seconds.
Can someone help me, so hotmail.com (and some others) can deliver his mails?

Thank you.
