Hi Martijn,

That might work, although i don't need to actually encrypt  
every recipient address but I do need to restrict emails to  
authorized recipients only.

Regards

Bruce

One option would be to add a DLP quarantine rule that matches all  
emails, for example add a matcher that matches .\* or matches one or more  
email addresses. This will result in quarantining all outgoing email. If  
you then want to \*not\* quarantine email from a specific sender you can  
disable DLP for that specific user (or remove the match all rule for  
that user if you want to keep DLP for that user with different rules).  
Disabling DLP in this case is a way to "authorize" certain recipients.  
If you want to "authorize" a domain you can disable DLP for the domain.

Is this more or less what you need?

Kind regards,

Martijn Brinkers
