running exchange server 2003 (SP2) and mail is being relayed from ISP to this exchange server. when i send a mail from my hotmail account to my mail address on this server it gets through and if i reply it hits the hotmail account fine. the problem is that if i create a new mail message within outlook and send it to my hotmail account, the mail never arrives and there is no NDR.
in exchange system manager, i have allowed the IP address of the ISP's mail server access and relay. it seems to work when i send a mail from hotmail to the exchange box but not when i create a new mail message.
appreciate any help/advice
