Why would you email Badspot about this? It's literally none of his concern.
Your webhosting provider should already have an SMTP server that is set up on your server. You really ought to contact them instead about this. If you're hosting from a VPS or from home try looking up some tutorials on how to set up SMTP on your OS, and also find an SMTP service since that isn't actually something you can really do yourself.
