Postfix is responsible for receiving emails and passing them to Dovecot for local delivery. Postfix also works as an SMTP server. So failure to receive emails on your system could be caused by several factors:

  • Lack of inbound access to port 25 (mail delivery port)
  • Incorrect Postfix configuration
  • Incorrect Dovecot configuration e.t.c I would advise you to seek the the help of a professional to troubleshoot the issue because it needs more analysis.
