Exchange must render hyperlinks from email sources from non-.mil domains as unclickable.

Active hyperlinks within an email are susceptible to attacks of malicious software or malware. The hyperlink could lead to a malware infection or redirect the website to another fraudulent website without the user's consent or knowledge. Exchange does not have a built-in message filtering capability. DoD Enterprise Email (DEE) has created a custom resolution to filter messages from non-.mil users that have hyperlinks in the message body. The hyperlink within the messages will be modified, preventing end users from automatically clicking links.
