ProSecure Web/Email Security Threat Management (STM) Appliance Reference Manual
2-16 Using the Setup Wizard to Provision the STM in Your Network
v1.0, September 2009
IMAP From the IMAP pull-down menu, specify one of the following actions when an infected e-mail is
detected:
• Quarantine attachment. The e-mail is not blocked, but the attachment is removed and
placed in the malware quarantine for further research. In addition, a malware quarantine log
entry is created, and depending on the nature of the malware threat, also a virus log entry or
a spyware log entry.
• Delete attachment. This is the default setting. The e-mail is not blocked, but the attachment
is deleted, and a virus log entry or a spyware log entry is created.
• Log only. Only a virus log entry or a spyware log entry is created. The e-mail is not blocked
and the attachment is not deleted.
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.
