error message. But so what? It doesn't break anything fundamentally.

Typically, you can also configure programs to not send mail.
For most purposes, log files are all you really need to keep a eye on
how the system is doing...
You can even read/send your personal mail from such a machine, if
you're using an external account (like a freemail provider or some such).
