Hi,
We've configured postfix in Ubuntu 16.04 that will relay mails to our mailserver. It is realying all mails through our mailserver. Mails belongs to other domains are not sending( Got bounced ) but ableto send mails belongs to our domain ( mcci.com ).
We've checked the logs of mail, it is clearly showing that the IP which is assigned in DreamCompute VM got blocked by symantec.
please have a look at the error message below:
