I'm about 1/2 a step above knowing nothing.
So this idea may be totally stupid, I apologize if so.
I am interested in implimenting a PHP based for mail.
Thus, I've been reading various post on here.
Most are well dated but seem to have MOSTLY good advice and examples.
In reading them, they gave me a idea. One that I haven't seen mentioned.
That in turn made me wonder if it's even feasible.
So I decided to ask, and maybe even spark interest that leads to increased spam/exploits security...
How about implimenting a dual/tri purpose timer?
set it with a minimum time, crashes if bots submit it to early
maximum time, does a preliminary time out if
TAKING (not taken) to long, so perhaps does a contact form refresh, or throws a security question, MUST BE ANSWERED, NOT CLOSED, then if answered correctly, restarts a additional time alottment to finish the msg.
IF ANSWERED WRONG, commits a die command to the mail script
PERHAPS EVEN, pull redirect to badbot trap
I imagine it is all possible.
