 * Problem with incompatibility between plugins.
   When using your plugin with the
   newest version of [Redirection for Contact Form 7](https://wordpress.org/plugins/wpcf7-redirect/)
   the website will return a PHP Fatal error: Cannot redeclare fs_dynamic_init().
   This is caused by the fs_dynamic_init() which is created by the PostSMTP plugin
   which doesnt check if it exists. When you check if it exists, and then not create
   the function, this error is fixed..but..the function that already existed will
   be used (in this case from Redirection for Contact Form 7). This will cause the
   next error because the function is completely different.So please prefix the 
   functions your using with your own prefix so it will not cause issues with the
   combination of other plugins.I’ve also asked the other plugin to prefix there
   functions ([see reply](https://wordpress.org/support/topic/latest-version-3-1-6-created-fata-error/#post-17838958)).
   Thanks in advance.Erik
