Enhanced Communication Security (FIPS)

Mail Express v4.0 and later allows you to use only protocols and algorithms for use by FIPS 140-2. The Federal Information Processing Standard (FIPS) Publication 140-2 specifies the security requirements of cryptographic modules used to protect sensitive information. (Toggling FIPS mode requires that you restart the server service.)

FIPS is not supported for the Outlook Add-In via the DMZ Gateway when the Outlook Add-In is installed on Windows XP.

To enable FIPS-compliant protocols

  1. Log in to the Mail Express Server Administration Interface.

  2. In the navigation pane, under Configuration, click General. The General Settings page appears.

  1. Under Enhanced Communication Security, select the Use only protocols and algorithms approved for use by FIPS 140-2 check box.

  2. Click Save. A message appears at the top of the page.

  3. Click Restart server now.
