- What server do you control Sender or Receiver? Both?
- Both using Sentora?
- Using http://verify-email.org/ does the Recipient account exist?
If you only control the Sending server, you can't do anything about it.
Great! your notificate There is a missing letter in Recipient's email address. Now it's working
Thank you So much
