[PHP-INST] Warning: mail() is not supported in this PHP build

[siamak]

Hello

When trying to send mail inside my PHP script I receive the following error:

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

What is the reason ? Compile errors ? Or my Host has disabled access to PHP
mail() function ?
How can I solve the problem ? Is there any alternatives to using mail()
function that may work?

Regards,
