Please help. I've been stuck for days. I am trying to configure postfix. It should be so simple. I just need to put in "myhostname =" and "mydomain =" However. I can't figure out what those are! Now, myhostname should just be my machine name, I think. But I don't think that will work, because it's not really a FQDN, I think. It is in the format of ip-192-0-2-0.ip.secureserver.net, which I don't think is working. Also, I don't know what my domain name is. I have several domains with GoDaddy, and this VPS server is set up to serve them all. The chief domain name, i guess is example.com, but I have tried that and it doesn't seem to work. Can someone help me figure out what I should put for myhostname and mydomain? I'm really sorry for the newb question. I have been trying tutorial advice for days and I just can't make this work.
