 : Refuse, Block, Tag or Route to DeadLetter Mailbox |

| JSpamFilter handles mail in essentially one of three ways: |
|
 |
|
 Block: Messages are blocked in effectively three ways as well: the connection can be refused, or the connection can be dropped
after determining through a DNSBL look-up that it comes from a black-listed server, or the message can be sent to a Dead Letter Mailbox.
Refusing the connection is stronger than dropping the connection in that the "drop" can be over-ridden by filter scores, whereas
a refusal is pre-emptive.
|
|
 Tag: Messages that are found to likely be spam, but fall in the "grey area",
have their subject lines tagged with [JSpamFilter] and are forwarded to the user to be sorted using email client rules and filters for convenient analysis. This lets the end-user have their
own "quarantine" which reduces clutter in their inbox, avoids false positives, and eliminates the inconvenience of logging into remote email quarantines as with a spam email filtering service.
|
|
 Forward Clean: Messages that are found to be clean are forwarded untouched. Note that JSpamFilter does not employ a store-and-forward
mechanism, all processes are done essentially in real-time.
