A very good article but even after setting up sqlmail in the same manner I still have an issue I haven't been able to resolve. I several hours on this an never figured out a solution. I setup everything as describe in this article and others. I could test the process and the first email would work as expected but any after that would que up somewhere and only be sent after a reboot. I test everything I could think of an it all worked properly but only one email would be sent.  I was accessing a Novel Groupwise mail server on the network. Any ideas would be welcome.
