I have a new server running ubuntu, nginx, php sendmail etc.
To test if sendmail is working I made a basic php file with the php mail function in it. When I execute the file my browser hangs until I get a 503 timeout but I still receive the test mail a few seconds later indicating sendmail is working.
Other pages on the server load just fine
The server does not have a domain name; I am just using its IP address for now. There are no errors in the nginx error log but the mail log is showing errors like
sergeserver sm-msp-queue: unable to qualify my own domain name
Any ideas why and how to solve?
Here is the contents of
