This should be easy.
I got a Windows 2003 server, and an ASPNET application. Point is, I want to send mail. I do not have an SMTP server available, as this is on a dedicated box somewhere. I setup the Microsoft SMTP service. Problem is: every time I sent an email, it is unable to relay. To fix this, I must add a domain alias for every possible domain I would send to. There has got to be a better way. Is the MS SMTP service not sufficient? If not, can anyone recommend a solution?
