i just installed msexhange 5.5 on a NT 4 server. our ISPs mailserver cannot re-route our e-mails from their server to ours. because they dont use exchange mailing system on their server, is it needed to point our MX record on their dns in order to recieve all our due e-mails on their server ? our exchange config is right for we can send outbound mails and local mails but cant received inound mails from our ISP. Please help me…thanks…
