Cannot send email via postfix / dovecot error status=deferred (mail transport unavailable)












0















I am trying to setup a mail server with postfix/dovecot/maria DB on centos 7 and have seem to hit a roadblock.



I am not able to send emails to internal users and the logs suggest "mail transport unavailable". I checked few resources online and dont seem to find help, the services are up and running.

          Personally I'd strace the qmgr process and hopefully see where the error is coming from.



          Is dovecot running?
          Does website-internal.com have a MX record?



          What happens when you run:



          echo "test" | /usr/sbin/sendmail -fuser@website-internal.com user@website-internal.com
