The biggest problem you'll run into is sending email from your residential internet connection. Most, if not all, residential ISPs either 100% block or severely throttle port 25 outbound traffic to cut down on spam. Even if you're able to find an ISP that doesn't block 25 outbound, if the reverse zone lookup indicates that it's a residential ISP most spam filtering solutions are going to flag all of your messages as spam.
