I remember that time, when a pretty big customer bought a tiny server from us and proceeded with setting up their tiny website.

Everything went smooth a smoothsauce until that day they decided to send a newsletter to 3 million subscribers - a complete nice email with alot of html and elements that was hosted on that tiny server.
The fact that most phones do download the emails with the attachment (pictures, html and shit) when the email arrive did they not know about. But sure - they atleast learnt something that day.

That shitty server died.
