Doesn't send SMTP email on localhost

If "localhost" is on your home network, then Massaki probably has the correct answer and your host likely blocks port 25. Most do. If you are on windows, there is a easy solution called "smtp4dev" if you google it. It's a small app that intercepts outgoing mail on port 25 and shows it to you in your email client so you can test even if port 25 is blocked.

I'd check this to see if it's blocked by your ISP:
