It was a shared host for different users. None of them wanted to manage another inbox, they just wanted incoming mail forwarded to their personal mail (gmail, hotmail, whatever). Compare to e.g. an outsourcing firm who wants their contractors to be reachable at duder@dudesinc.com, but doesn’t want them all to have to manage another inbox. This is very hard to achieve, due to the problem mentioned above. This was not an actual business , just friends playing around with servers back in uni. But it made me realise this is a pretty fundamental issue with SMTP. The protocol is doomed to centralise.
