Though the message says that it's
From: "La Aurora Gallery" <firstname.lastname@example.org>
it really isn't from email@example.com. Looks like someone
just used your email address. This can happen when people
want to cloke who they really are. It can easily be done
by using a web browser to send the email. You can set your
identity to be anything with a browser.
Seeing the following in the bounced email makes me think
that the mail machine of ethernetix.com saw that the
email was not actually coming from art.net... see:
>Article rejected, un-authorized poster of firstname.lastname@example.org
>Received: from wmail.prtc.net [18.104.22.168] by
mail.ethernetix.com with ESMTP
There's not alot you can do to stop people from doing such things
though. People who send spam used to send it from addresses and
domains that didn't exist. But postmasters of sites have caught
on and reject such email. Looks like this postmaster went a step
further to make sure that email actually originated from art.net.
And since it didn't, the email was bounced.
I am currently working on getting a mailer addition to art.net's
sendmail that will prevent people from sending spam to anyone
Please let me know if you have questions.
