I am setting up a new business and have no Linux admin yet. I have used Fedora for a couple of months and have basic knowledge of it. I reserved a domain name hosted by godaddy.com and am able to send emails from my Fedora server using Pine. However, when I send my email messages to a Yahoo! account, they arrive and get put in the Trash box. I've heard that it has something to do with email relaying.
I am looking for help with the following:
1. Change configuration to make sure that my email messages don't get put in Trash of the recepient's side. I believe I am using sendmail to send email messages from the server, but how do I confirm this?
2. Configuring my Fedora server so that I can use my Outlook client to retrieve emails from it.
I would really appreciate some help or at least some links to existing information on how to set up a primitive email server on Fedora. Maybe Fedora comes with some system tools that could help me do that?
