You can test a spam scanner / filter by adding the following code to the body of your email

{code class='brush: text;'}XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X{/code}

• If your anti-spam detects it and marks it as spam then it's working.
• This is a generic spam test string.
• If it does not get filtered by your email client, it might be that you email client is ignoring the spam headers in the email or it is not sufficiently high enough.
