I'm learning how to use php. One of the tutorials is about sending email which requires sendmail to be turned on. Can someone offer an easy explanation on how to do this?

thanks

Sendmail is "turned on" and ready-to-go with Snow Leopard already.

If you're having problems with sendmail functioning correctly with php's mail() function, try reading the following:
