above. But at times it happens that the receiving smtp server refuses to
accept mail from the sender since the sender is not known to be a good
smtp server, and at times it could get blacklisted. Rules like this get
tightened up because of the desire to curb spam at the source.

So, say I did go and setup a local SMTP relay, how would I make it
known that it was a "real" smtp server and not just some script
pushing spam?

You can use SPF, DomainKeys plus valid DNS information.
I have setup SPF records for my domains. If you attempt to send E-Mail as if it was sent from my server then any server doing SPF record checking will not accept or simply drop your message.

I have not setup DomainKeys since SPF has served me well but I will configure it soon.
