lot of web hosts (like mine too) disables php mail() function so people hosting their websites can not send mass emails as sending thousands of mails in one go can bring down the shared server on its knees. But by disabling mail() function, hosts also disable software and programs which are written with mail() function to send mails.

A good example of this is wordpress notify plugin using which a commentator can subscribe to the comments of any posts, so now after his comment, if anyone makes a comment, he will get a notification. The problem is, with mail function disabled, he won’t get any notifications so the workaround for this given by wordpress community is to use wp mail smtp plugin.

The plugin uses SMTP and wp_mail function instead of mail function of php which helps your mail reaching to your readers and comment subscribers. The installation of the plugin is very easy, just download it and install it. It is written the plugin page that it is only compatible with with wordpress 2.7 and higher but I have used it with older version of wordpress and you can also find the older version fo the plugin compatible with your wordpress installation though the smart thing will be to upgrade everything.
