For the Mail functions to be available, PHP must have access to the
sendmail
binary on your system during compile time.
If you use another mail programm, such as
qmail
or
postfix
, be sure to
use the appropriate sendmail wrappers that come with them. PHP will
first looc 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
permisssion to access the sendmail binary.
