SYMPTOMS
When you are using Antigen with Advanced Spam Manager (ASM), spam that has &quot;re[10]&quot; in the subject line is not filtered.



CAUSE
This issue occurs if you are using a subject filter character set that has multiple digits. Character sets allow for single digits only. For example, the filter &quot;re \[[0-9]*&quot; will not filter an e-mail message that has &quot;re[10]&quot; in the subject line.



RESOLUTION
To filter an e-mail message that has a subject that has a single digit, use the following filter:

re \[[0-9]*

To filter an e-mail message that has a subject that has double digits, use the following filter:

re \[[0-9][0-9]*

To filter an e-mail message that has a subject that has triple digits, use the following filter:

re \[[0-9][0-9][0-9]*
