"Email Filtering and Traffic Control
Filtering is a feature that enhances SMTP security within TFS Secure
Messaging and safeguards against the unauthorized mailing of
proprietary company information. Email can be filtered by sender,
receiver, domain name. IP address, key words within the content of the
email text, attachment size, attachment type and mail flow....
...Attachment Filtering
Filtering by attachment size and type can prevent large or potentially
dangerous attachments from being sent or received, such as .avi or
.exe files. These files are usually large in size and slow down
network processing by consuming bandwidth. The application also
enables the server to search attached files such as .zip files for
predetermined words or phrases within more than 300 different file
attachment types.
Example of Use:
You need to stop a disgruntled former employee from flooding your
mail server with multiple large files and crashing your network.
You are concerned that company confidential documents are being
renamed and sent as .zip files to a competitor..."
