Spam Classifications

The following table describes the possible Spam classifications that Commtouch can return in response to a request from the querying devices.

Classification

Explanation

Confirmed

Spam messages from known spam sources (e.g. zombies).

Bulk

Spam messages from sources that are not confirmed spammers.

Suspected

Legitimate messages that are sent to slightly larger than average distribution or are unidentified spam messages in the first few seconds of a massive spam outbreak.

Valid Mail

Messages for which Commtouch does not have any incriminating information, and are therefore assumed to represent legitimate correspondence.

NonSpam

Messages that are confirmed, without doubt, as coming from trusted sources. This classification is very rarely used.
