 * Hi
 * sorry for the delay, I had to get a vultr server 🙂
 * 1. Press on the server row.
    2. on the upper menu select “settings” 3. on the“
   Reverse DNS” column press the pen icon and replace the text with the domain name
   your hosting or any valid domain like clients.mywebsite.com
 * You will need to wait a bit so the DNS change will take effect.
 * What happen?
    In the last version, I had to change the mail ID from an IP to 
   hostname for a better compatibility with spam filters and the RFC rules.
 * Vultr giving some kind of a fake record in each server creation and the user 
   needs to change it manually.
 * Please update me.
