I'm getting a 'relay access denied' error when attempting to send email to one of my accounts. I have read all the posts here for the last 1 year that have to do with 'relay access denied', I've read the support wiki, and I've searched on the web for other resources. I have tried a few things. Nothing seems to work, and I am completely confused.
I have a friend, Friend1, who registered a domain, Domain1, at GoDaddy.com. On Friday, I set up hosting for her on Dreamhost.com. I created a mail address called 'mail' that only forwards to my friend's Gmail address. We've tested this setup, and it works perfectly.
I have another friend, Friend2, who registered a domain, Domain2, at Orcon.net.nz. On Saturday, yesterday, I set up hosting for him on Dreamhost.com. I created a mail address called 'mail' that only forwards to my friend's Gmail address. We've tested this setup, but all email sent to mail@Domain2 bounces back to the sender with the 'relay access denied' error.
I don't understand why these two situations should work so differently when all that's different is the registrar.
For Friend2, do I need to add Custom MX Records here on Dreamhost? If so, should they be MX records from Orcon.net.nz?
Or do I need to add Custom MX Records over on Orcon.net.nz? If so, what should they be? Is Orcon.net.nz really even involved at all in the delivery of email, since Domain2's nameservers are set (on Orcon.net.nz) to the Dreamhost nameservers?
Please, someone help me understand exactly what I need to do in order to fix this 'relay access denied' problem.
