Table 4-4. E-mail Anti-Virus Exception Settings
Setting Description
Scan Exceptions
From the pull-down menu, specify one of the following actions when an e-mail attachment exceeds the
size that you specify in the file size field:
• Skip. The file is not scanned but skipped, leaving the end user vulnerable. This is the default setting.
• Block. The file is blocked and does not reach the end user.
The default and maximum file sizes are:
• For the STM600 and STM300, the default setting is to block any attachment larger than 10240 KB.
The maximum file size that you can specify is 51200 KB.
• For the STM150, the default setting is to block any attachment larger than 8192 KB. The maximum
file size that you can specify is 25600 KB.
Note: Setting the maximum file size to a high value might affect the STM’s
performance. NETGEAR recommends the default value, which is sufficient to
detect the vast majority of threats.
