I use the free version of 000webhost for three months.
Since before yesterday, I noticed that all the mails that I send from my web site are redirected in my mailbox (mailbox of creation of my 000webhost account). I want to understand.
Note:- 000webhost does’t provide “Email Accounts”, only “Email Forwarding”.
Email forwarding allows you to forward email from an email address at your domain to another address.
For example, you could create an address email@yourdomain.com to forward mail to your current Gmail, Yahoo address where you would actually pick it up.
