Hi All, I just installed FC3 and used yum to install all the patches and updates. The system is now running the 2.6.9-681 kernel. I started up Evolution and went through the wizard to setup the email account. Once I finished I sent a test email to myself. Evolution prompted me for my pop password and then successfully download my email. When trying to send the test email it returned with a 'mail from user unknown error'. I've seen previous threads and postings on this but no resolution. Has anyone else experienced this problem or know a fix? Thanks! Kevin Lisciotti, CISSP
