I've written a mail program for Windows 2000 . I'm using cdosys.dll. I want to use the same program on a Windows NT machine for which I've to register cdosys.dll in Windows Nt machine. In some machines I'm unable to register this dll. Is there any other supporting dlls which I should register?
I was able to register in a few machines, but then I get the following message..
The server rejected the sender address. The server response was: 454

Can anybody help me out
