mail() Function not working After PHP Upgrade

[ElijahT]

Just a few hours ago I sent a request to have my PHP version upgraded. It was accepted, and since I received an email saying that everything was set up and should work properly. Unfortunately, this doesn't seem to be the case. I'm looking to use Drupal as a base for my site, but it seems unable to use the mail() function. After registering my email, it redirects me to a blank page. Upon returning to my Drupal site, it says that the mail() function is disabled. Any help would be appreciated.

It takes up to 4hours for it to take affect onto your site - and in some rare cases it can take 24hrs.

As Flashgear has told you, it takes approximately 4 hours for changes to take effect. Post back if you still get the error.
