When a spam message arrives in your inbox drag it to your new isSpam folder!
When DSPAM determines that a message is spam it automatically places it in your Quarantine folder.
Check your Quarantine folder from time to time - especially at the beginning when DSPAM is learning your email - and drag good email which shouldn't be in the Quarantine folder to the isNotSpam folder. Within a few minutes DSPAM will learn that this message isn't spam and will place it back in your inbox.
Delete spam messages from your Quarantine folder. Once a spam message is in your Quarantine folder there's no need to save it.
A quick recap: If a spam message arrives in your Inbox then you drag that to your isSpam folder. Within a few minutes DSPAM learns that message is spam and then moves it to your Quarantine folder. You also want to occassionally scan your Quarantine folder for non-spam messages and move those into your isNotSpam folder. After a few minutes DSPAM willl learn that those messages are not spam and will place them back in your inbox. You can, and should, delete spam from your Qurantine folder since there is no need to save this spam.
To review: Place spam in the isSpam folder and drag misclassified real emails that were Quarantine'd into theisNotSpam folder.
And give it a few days and watch the magic happen!
- DSPAM does NOT work with Outlook 2013 and Outlook 2016. New versions of Outlook strip message headers from email when messages are moved from folder to folder (so wrong, so bad!) This Outlook behaviour removes DSPAM header information which effectively disables server-side spam filtering.
