Block Attachment: The software should allow system
administrators to block specific attachments types of specific
types (for e.g. .doc, .exe, etc.) from being sent or received.
This puts an end to important documents like source codes,
sales figures, annual accounts, etc. from being e-mailed.
Auto Compress Attachments Software should automatically
compress, outgoing and incoming attachments. This saves valuable
bandwidth. There also has to be an option that allows you
to exempt specific attachment types from auto compression.
Options for Attachments Auto Compress: Advanced options
for auto compress should allow you to:
- Select minimum size of attachments, above which
it should be auto compressed.
- Select minimum compression % below which attachments
should not be compressed.
- Select the compression level that best suits your
need: Best Speed and Best Compression.
Following figure shows a screen with features to block and auto
compress attachments, from eScan email and Web Filter, the top
selling Content Security software.
