How do you know? SMTP wasn't designed for reliable delivery. You don't know if your emails are being received, and even i they are, you don't know if they'll be received tomorrow.

- johnklos 4y agoIf you're not getting bounces, then the receiving email servers are not RFC-compliant. If you're really that worried about it, smarthost.
