smtp.earthlink.net is the name of the computer at Earthlink which sends
your outgoing emails. ISPs these days have all sorts of newer security
features ("authentication," and other tricks of the trade). "Relaying"
is sending email using an smtp server other than the server of the
ISP/email provider at which the SENDER of the email --as the smtp server
recognizes the sender, which is NOT necessarily the same as you as seen
by the smtp server -- is duly registered as the user.
I'm not sure technically all the ways this can be effected by the smtp
server (such as checking and comparing the various headers, To:, Reply:,
etc.), but anyway, if for whatever reason your smtp server decides the
particular piece of email is NOT really being sent by YOU, it will
generate this error.
For example, I have an email account at a freebie email website
www.hotpop.com (which is quite a good service, by the way, if anyone is
looking for setting up extra eddresses!), and I received an email
downloaded from there by Emailer. I wanted to bounce (not forward) the
email to someone using hotpop.com's smtp server (as opposed to my own
ISP's server.) Hotpop's smtp server gave me the error you got, because
of the way it checks headers, it didn't recognize that I was the person
doing the bouncing; I think I ended up forwarding the email, and the smtp
server let me do that.
As to why it is happening in your particular case, it could be anything
probably from a temporary glitch to something you are doing and maybe not
realizing it.
