Not that I needed it (as nothing goes wrong here without mutt :-) but thank you for the explanation. It's more authoritative than shouting "Is! Is not!"'s back and forth. I know MIME is for selecting view clients at the receiving end (which does require the right tagging at the sending end). I was focusing on the PDF format. Of course, I didn't realise that the wrong tagging is not supposed to damage the message payload. [snip; self-censorship on speculation of potential cause] Sorry Ben for tickling your challenge bone and triggering such a long but friendly response from you. I think this should do, Tibor (not suggesting you should listen to me ;-).
