Problem with new legacy package in RedHat 9.0 with php...

["Jim van Wel" <info coolzero info>]

I have a major problem with the package php-4.2.2-17.5.legacy.i386. It
doesn't support the mail() function anymore? Am I doing something wrong, and
if so, what can I do to fix it?

I get an error like this:

Warning: mail() is not supported in this PHP build

Hope to hear soon about this matter.
