This plugin allows you to set the email address and name used on email sent by wordpress by setting the From: header. Adds a “wp mail from” section in the “settings” menu The plugin uses the filter hooks wp_mail_from and wp_mail_from_name. I believe these are both available in WordPress 2.3+ The priority for the hooks is set to 1 to allow for other plugins that may hook these with the default priority of 10 to override this plugin.
