When I installed Fedora 5, Sendmails SMTP port option was configured as localhost. I use Webmin for most of my configuration, so in Webmin I switch it to "default". Maybe you have the same problem. And after that all worked like a charm.... SMTP port options: This option allows you to configure what IP address and port the sendmail server listens on. For details of the possible values for this option, see the sendmail documentation.

It is odd that sendmail is not working either. I have no firewall or SELinux, and all ports relevant are open. Thanks Best regards Mike Hayward
