We have Lotus Domino R5 installed on our NT4 server. I just changed the DNS server to MS DNS server, the previous one is called DNS BIND? I am sure it is well configured, but finally I we found that we couldn't send email out. But we couldn't get any rejection error. Then I changed it back to its original dns server, all the email we had sent were sent out.<br>I am quite new to Domino email server, could anybody here enlighten me?<br>Thanks a lot!
