Send all outgoing emails to text file or 1 email address?

[edoyax]

I want to test a bunch of PHP applications on my test web server that send emails to various email addresses, and instead of them going to the different addresses I would like them to either go to a gmail account or to a plaintext file on the web server.

Does anyone know of a configuration or sendmail replacement that I could use to achieve this?
I am using Windows as the test web server's OS and using SMTP for PHP's mail() function currently.

If you want them to go to a gmail account you could just change the to address from the various addresses to the gmail address. If you're getting your various email addresses from a database or something just change the code that you're pulling the email addresses from.

If you want to output the message to a text file you would just have to use fwrite.

Posting code would be helpful.

Well the objective was to not change any code but to change the backend for PHP's mail function.
I have a 100+ scripts that use the mail() function and I don't want to have to switch things around at all. I just need something that will let the mail() function return true as though it sent the message and actually output the message somewhere so I can see it.
