There are two methods used to identify these emails to you. First, the subject line of the affected email will be prefixed with one of the following:
{Spam?} - indicates that the email is likely to be spam - you should filter these emails into a separate folder in your email client. {Definitely Spam?} - indicates that the email is almost definitely spam because it got a very high detection score
- you should filter these emails into a separate folder in your email client.
Second, additional headers are added to the email: X-WTTW-SpamCheck: spam - indicates that the email is likely to be spam and contains information on how the score was reached. X-WTTW-SpamScore: ssssss - indicates the spam score for the email. Each s represents 1 point, so sssss indicates a score of 5. The service has a threshold of 5 for {Spam?} and 20 for {Definitely Spam?}
