Hello, I created my own mail server client my domain name is www.softmail.me from this mail client I can able to send emails to any email provider but I cannot receive any emails back.

I hosted my client at http://beta.softmail.me do I need to apply settings of a sub domain or domain settings are enough.

Kindly check my dns settings and reply me.

my DNS details are

A (Host)

host = @ points = 65.75.241.26

host = beta points = 65.75.241.26

host = accs points = 65.75.241.26

host = mail points = 65.75.241.26

host = stable points = 65.75.241.26

CNAME (Alias)

host = imap points = mail

host = pop points = mail

host = smtp points = mail

host = www points = @

Please verify the above settings and tell me why I am unable to receive emails back from other email providers.
