	the malware threat. You can change the default message to include more
	information.

	enable the UTM to insert the correct malware information. In addition to the
	%VIRUSINFO% metaword, you can insert the following metawords in your
	customized message: %TIME%, %PROTOCOL%, %FROM%, %TO%,
	%SUBJECT%, %FILENAME%, %ACTION%, %VIRUSNAME%.

Email Content Filtering

The UTM provides several options to filter unwanted content from emails. You can filter content from emails based on keywords in the subject line, file type of the attachment, and file name of the attachment. You can also set an action to perform on emails with password-protected attachments. By default, email content filtering is enabled.

Several types of email content filtering or email blocking are available:

•Keyword blocking. You can specify words that, should they appear in the email subject line, cause that email to be blocked by the UTM.

•Password-protected attachments. You can block emails based on password-protected attachments such as .zip or .rar attachments.

•File extension blocking. You can block emails based on the extensions of attached files. Such files can include executable files, audio and video files, and compressed files.

•File name blocking. You can block emails based on the names of attached files. Such names can include, for example, names of known malware threat such as the Netsky worm (which usually arrives as netsky.exe).
