Hi everyone, hope somebody can help me out with an answer its probably really obvious to most of you... Whats involed with setting up a SMTP outgoing mail server, in terms of an ISP, once they build the server its self whats after that where would the outgoing mail be sent. I assume it would be a dns server. but would love if someone could explain this to me thanks in advance.

not quite sure if you ask in general or if theres steps you have to do in general, when a mail gets send, the mx entry of the dns server for the recipient domain is checked, and the mail is send to the corresponding ip. if theres multiple priorised mx entries, it will first try to conntect the highest prio mail server and fall back to the lower ones if the higher prio one doesnt answer. if you set up an outgoing smtp locally and want to send via your isp, you would configure your isp's mail server as smarthost. theres a kb with some overview: http://support.microsoft.com/kb/303734/en-us did that answer your question or did i understood you wrong?
