E-mail Content Filtering

The UTM provides several options to filter unwanted content from e-mails. You can filter content from e-mails 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 e-mails with password-protected attachments.

Several types of e-mail blocking are available:

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

•Password-protected attachments. You can block e-mails based on password-protected attachments such as ZIP or RAR attachments.

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