Confirmation of receipt

[#1]

Hi,
I sometimes get  an email that requires me to confirm receipt before I can open it, by sending a message to the sender. How can I set up this facility for my own use?
Thanks

What email client are you using?

[#3]

Squirrel, via Plusnet

[#4]

Go to Options, Display Preferences. There you will find Enable Mail Delivery Notification. When that is on you will see boxes to tick to request receipts when you compose messages.

Thanks, will try that.

Is this right?  I've never been asked for a read receipt that wasn't optional -- i.e. I could refuse to send one and still open the email. Is there anything in Squirrel that distinguishes between the optional and the mandatory when requesting read receipts?

Well if I send an email from Webmail with a read receipt request, then I still have the option to ignore it when viewing the message using Thunderbird.

As far as I'm aware, read receipts are always optional, whatever the mail client. You just hit the Ignore button and you will still be able to see the email.
