Suddenly at some point, I wasn’t able to send any e-mails. Messages got stuck in the outbox, refusing to leave my computer.
At first I thought it was a temporary problem with Google’s mail servers, as I hadn’t installed or changed anything for a week or two on my own computer.

So I ran the following command:
No greeting or anything. The telnet session just hang there.
