November 3, 20205 yr As the title states, I'm having difficulty setting up mail on my Ubuntu VM. I have a small home network and in addition to my unRaid box, I have a standalone PC running Ubuntu in which I have successfully set up Postfix and I able to send mail. When I attempt to send mail from my Ubuntu VM, it results in the error "dns=5.0.0, stat=Service unavailable." I have basically copied my Postfix config from my working Ubuntu installation, but apparently I'm missing something unique to the VM installation. In the vm I have set my host name as the fqdn. Any thoughts? As an afterthought, I have apps running on the vm which have built-in mail capability which are successfully sending email notifications so I suspect it's a Postfix or Sendmail mis-configuration. I would like to get this working as I have BackupPC running on the vm and it can only send email notifications through postfix or another mta. Edited November 3, 20205 yr by Woodpusherghd
