PHP mail() function does not work on ISPManager servers

[Chains]

We've used ISP Manager for a while and have never been able to get mail() to work in php. This means that blogs installed on the server cannot accept contact form emails and comment notifications don't arrive.

How do we fix it so the server can send mail? This works in a default installed lamp stack, but even after numerous Google searches I can't find a solution.

Thanks.

This has nothing to do with Yahoo mail. The server needs to send mail using the PHP mail() function. The server also sends email with mail boxes for users of the various domains on the server like:user@example.com.

This also has nothing to do with Outlook. This is the server not being able to run this code: test.php

<?php mail ("you@example.com","test subject","This is a message.") ?>

What you see in the email server logs? See /var/log/maillog or /var/log/exim4/mainlog when you run php script with email function.

Thanks for help.
