alternating email addresses using formmail

[Crucial]

I am trying to make my take an incoming formmail application and alternate the results to two seperate e-mail addresses? I get leads in from my website and I want a fair, and automatic way to pass them out to two people. The first one would go to email1@ and the second would go to email2@, the next would go to email1@, and the following over to email2@. If I can avoid using a database, that would be even better. Any help would be greatly appreciated.

 

I heard that I can use PHP to make this happen, but I have no idea what the code is or what the keywords are to search for the code.  Does anyone know what I need to do to make this happen?

 

I use Formmail and whatever the code is, would it happen on the html page, or the cgi script that makes it work.  Any help would be greatly appreciated.

 

Thanks,

Mike
