My sent e mails are delivered but disappear from my sent box. Is it a setting issue. How do I resolve it

I'm assuming you're talking about BB10. If you compose an email and send it, it should definitely appear in your hub. It should have one of three icons next to it:
✓ (A Check or Correct) Mark which means that the email was sent and delivered successfully
X Mark which means that the email has failed
⏰ (A Clock/Watch Icon) Which means that the email is still being sent/delivered

I have had the same experience with emails in the past. I would send them, they would show up with the ✓ (Check Mark) Icon for a few seconds then disappear. The recipient always received them though. I use Gmail as well as other services
