Hi Alexander, >From what my ISP has told me, the SMTP server has no authentication and is configured to accept any email from within its domain. The funny thing this that I also have Novell Linux Desktop 9 with Evolution and that sends mail just fine. Also, my wife's XP machine using Outlook send mail ok as well. I believe it to be an FC3 issue. I'll use a sniffer and see what the traffic looks like.
