Some do, like Thunderbird. Some don't, I'm told. The particular
client I usually use, 'mutt', doesn't respond to them at all.
(Yes, it's a crusade. One of the very few principles of mine
that the modern internet hasn't destroyed yet.)

Just curious, but don't e-mail clients ask you
whether you want to send
the acknowledgement or not? I know Thunderbird asks.

Oh, I see.
The mail you are trying to deliver to me has a "Disposition Notification
To" header line in it. This is a common trick used by spammers to
prospect for valid mailboxes, because its purpose is to send the
message sender an acknowledgement as soon as the message is opened
by the recipient, whether the recipient wants to tell you that
they've looked at your message or not.
I don't allow mail wanting those acknowledgement messages because
I believe they are a privacy violation, so yours is getting rejected.
Delete that line from your email header and you'll get through just
fine.
