mail finction on NT not working

Hi there list people. I need help and lots of it. I have been using Apache and php on Nt for a year now and recently have written some code using the mail function. Problem is it does not work. Well the mail function does not work. My mail postoffice is Post.Office from Software.Com and it works fine. But for some reason even the test code I have copied from various sites does not work. I checked teh ini fail and I am pretty sure that it is set up correctly but then what do I know? Anybody out there have any ideas?? Please!!!!!!
