tricky question with windows and unix mix

[sks1024]

I am getting ready to start a new job the has all windows servers except one redhat linux email server(which is the only email server). When I arrive I am going to install PHP on the Windows server for my work ia m doing on the website. One question I have is how to I set up the sendmail in php.ini Since PHP is installed on a windows machine I am assuming I cannot use /usr/lib/sendmail in the php.ini file How would I go about setting this up.

Thanks,
Stan

...pretty simple really.... you can use a QDN (qulified domain name) in the php.ini file. For instance it may be smtp.aol.com or mail.aol.com or theLINUXbox@yourDOMAIN... never tried just using an IP addres but it should work...
