spamBlocker
spamBlocker categories
The Commtouch Recurrent-Pattern Detection (RPD) solution classifies spam attacks in its Anti-Spam
Detection Center database according to severity. spamBlocker queries this database and assigns a category
to each email message.
spamBlocker has three categories:
The Confirmed category includes email messages that come from known spammers. We recommend you use
the Deny action for this type of email if you use spamBlocker with the SMTP proxy, or Add a subject tag if you
use spamBlocker with the POP3 proxy.
The Bulk category includes email messages that do not come from known spammers, but do match some
known spam structure patterns. We recommend you use the Add subject tag action for this type of email, or
the Quarantine action if you use spamBlocker with the SMTP proxy.
The Suspect category includes email messages that look like they could be associated with a new spam attack.
Frequently, these messages are legitimate email messages. We recommend that you consider a suspect email
message as a "false positive" and therefore not spam unless you have verified that is not a false positive for
your network. We also recommend that you use the Allow action for suspect email.
