 * I am assuming this is a blocking script, correct? Is there some way to make it
   non-blocking?
 * A request that hangs would cause PHP to hang as well. Using an SMTP relay there
   is very minimal overhead and the script can continue while the SMTP relay is 
   sending the email.

 * Hi Jim,
 * I’m not sure I understood what you mean.
 * The whole point of this plugin is to use the Amazon API, not an SMTP relay.
    
   If the Amazon API is down, mail won’t be sent, but the WP blog won’t become unresponsive.
 * If you want to go the SMTP route, you can configure WP to use a SMTP host instead
   of the default wp_mail function, and use amazon SES smtp credentials.
