Obsoleted by bayesian junk mail feature and filter by addressbook.  (11/14/2002)

Last updated: 10/11/2001

 2
Creating a nsBlockSenderService (infrastructure)
  • persistant storage into a plain text file of all the blocked addresses. Try to keep the file format generic enough to eventually support domain blocking.
  • maintains the list of email addresses in sorted order in memory. 
  • provides data to the blocked addresses list outliner view
  • Hooks into the end of the filter process and then performs a log n search through the list of blocked email addresses looking for a match.
  • Ability to move messages to the junk mail folder.
  • APIs for adding and removing blocked addresses (called from the blocked addresses list dialog)
 varada
Folder Aging
  • We may not be able to get to folder aging for this release. If not, our fall back is to just support an empty junk folder menu item.

Total Man Days:  8 days

Risks / Unknowns
Folder aging is at risk. We may not support that as part of block sender. Instead we'll allow you to empty your junk mail folder. In order to minimize risk for the implementation, we're going to first implement the back end (nsBlockSenderService). This would allow us to get this feature working without any UI. Testers / developers could then manually add or remove entries in a plain text file and then verify block sender functionality. This can then land on the trunk and we can then start phase II which is the UI support for this feature.
