Processing Fetched Mail

At this point in our PyMailCGI web interaction, we are viewing an email message (Figure 17-12) that was chosen from the selection list page. On the message view page, selecting an action from the pull-down list and clicking the Next button invokes the script in Example 17-9 on the server to perform a reply, forward, or delete operation for the selected message.
