I performed a fresh install of Mail In A Box using the following configuration:
- Domain name purchased from GoDaddy
- Hosting on Digital Ocean
I completed the steps in the entire setup and configuration. The problem is that I can only send/receive emails using the one user I created during the setup (for example: email@example.com.
When I use this mailbox to send to my other mailbox or send email from my other mailbox to my Mail In A Box email address, I do not get any emails. I’ve done the steps of checking status page which shows everything as green except the SSH, re-installed Mail In A Box, rebooted the server and I still cannot get it work. The domain resolves correctly and I can ping it including accessing my control panel using the domain name. I just cannot send or receive external emails.
I also checked and confirmed using MxTools that I am not blacklisted. Everything looks correct using these tools.
Any help is much appreciated.
