Re : Mail features
On linux, you need to have sendmail (or something equivalent) installed
from the php doc : "PHP must have access to the sendmail binary on your system during compile time. PHP will first look for sendmail in your PATH, and then in the following: /usr/bin:/usr/sbin:/usr/etc:/etc:/usr/ucblib:/usr/lib. It's highly recommended to have sendmail available from your PATH. Also, the user that compiled PHP must have permission to access the sendmail binary. "
