Don't send emails to yourself. I sent an email to myself once, and discovered I can be a real prick, sometimes.
Kidding aside, Rob and I tried this out decades ago. He was able to send to my account, but my Cox account prevented my emails from reaching him. There are ways around security issues, like slaving with firefox headers when trying to get onto secure https sites with QB64. Sorry I can't be more specific, as this was stuff I messed with too long ago to recount the results. My point is, it ain't easy if your ISP is an SOB.
