Hot off the presses is the detailed version of the IBM Software E-mail Processing System (EPS) Help:
The E-mail Processing System (EPS) is a tool to allow registered users of IBM Software products to submit and track problems with IBM Software Support engineers by using plain e-mail. EPS is one of several ways you can submit and track problems with IBM Software Support. Other ways are by telephone and web. You may submit and track a problem by telephoning a contact center in your region.
And now you can easily find help in this detailed document, or even get a compact version of this document's Help information by sending an e-mail message to firstname.lastname@example.org with the subject line HINTS.
