I have a server with Ubuntu 14.04LTS. I am sending email from Ubuntu to email.test.com and then to my Windows PC account with Outlook, but I changed the domain for this post to test.com. The email sends and I have no errors in my SMTP log but the emails are not getting to my PC account.
I can ping email.test.com but that only tells me the physical machine is running. How can I tell if the email server is running if there are no errors in my SMTP log?
Thank you.
