Test mode for email

[Joel Peshkin]

It seems that, whenever I try to test new changes on the database from 
my live site, I have to do some hack to prevent sending spurious emails 
or to ensure that the emails go to me instead.  This is especially 
important when testing email notification changes.

I cannot possibly be the only person with this problem.  Should we....

a) Provide a param or config variable to force ALL mail to be sent to a 
specific address (even though the To: in the message will point to the 
actual user)

b) Provide a mechanism to force all mail to be written to a file instead 
of sent

c) Continue to hack around the problem
