34 CHAPTER 3: CONFIGURING MAIL SECURITY

Attachment Control Attachment filtering can be used to control a wide range of problems

originating from the use of attachments, including the following:

■ Viruses — Attachments that can potentially contain viruses can be

blocked.

■ Offensive Content — The 3Com Email Firewall can block the transfer

of images which reduces the possibility that an offensive picture will

be transmitted to or from your company mail system.

■ Confidentiality — Prevents unauthorized documents from being

transmitted through the 3Com Email Firewall.

■ Productivity — Prevents your systems from being abused by

employees.

Select Mail Delivery -> Attachment Control from the menu to configure

your attachment types and actions.

■ Default action — Set the default attachment control action for items

not specifically listed in the

Attachment Types

list. The default is

“Pass” which allows all attachments. Any file types defined in the

Attachment Types

list will override the default setting.

■ Enable Attachment Control — Select the check box to enable

Attachment Control for inbound and/or outbound mail.

■ Attachment Types — Click Edit to configure the attachment types.

■ Action — Select an action to be performed. Options include:

■ Just log: Log the event and take no further action.

■ Reject mail: The message is rejected with notification to the

sending system.

■ Quarantine mail: The message is placed into quarantine.

■ Discard mail: The message is discarded without notification to the

sending system.
