I use Ubuntu on my desktop box. I downloaded a backup script to trial. I thought, my work is on my desktop box, and I want to backup it up to a remote machine. So I downloaded the script to my desktop box, configured it, ran it, and it didn’t work. I couldn’t be bothered checking the debug output, so I just turned on the email error messages and sent the errors through to my email for me to review.

No email arrived. I thought, ok, maybe I’ve messed up the DNS on my local network for my mail server. Nope. All good. I also tried sending to a different account, but no email arrived. I checked the mail queue, to see if it was being sent out via the local SMTP as is often done, only to find that Ubuntu did not include an MTA!

Linux with an MTA is just not Linux. It’s just silly.
