Success Outcomes of Using External Sender Email Disclaimers

[Mark Janowiak <mjanowiak () HILLSDALE EDU>]

It seems the addition of external sender disclaimers on emails from outside an organization seems commonplace now.  I 
wonder if anyone has performed any credible studies to determine if this type of disclaimer actually influences 
behavior in the way we all hope - reducing the number of people who fall victim to phishing or spoofing? If so, how 
effective are they over a longer period of time? Have you seen them become less effective as people become accustomed 
to seeing them on every external message?
