Mail Delivery Subsystem <firstname.lastname@example.org>
Who’s “mailer-daemon” – I’d just like to know,
returning my words from where they should go.
Not nice in the least – just turns them around,
no reason is given – just back and shut down.
No “Might you try this” or “Might you try that”,
but rather just rude – somewhat of a brat.
If met face to face – would just have to say,
how would you like to be treated that way?
