return receipt not working
I can send email to my self or to friends with either or both Return receipt and or delivery receipt set. Have looked at the header of the sent message and all I can find is a line that reads "Disposition-Notification-To: Frank Holland <my [email protected]>" which is probably the request for the receipt. I have checked under options advanced for the handling and generation of receipt and can find nothing untoward yet no receipts seems to be requested or sent?? Haven't used this feature for a while so perhaps it got nobbled during an update? Any Ideas?

Most servers don't honour DSN. This is, I think, the disposition header component.
Some servers silently drop Read Receipts, so it depends on whom you are sending to. Gmail recipients, typically, will not get your Read Receipt requests. If you're sending through Gmail, it's likely these requests are redacted when you send the message and so will be absent from your Sent copy. If you set Thunderbird to save to a Sent folder in Local Folders (and thereby prevent Gmail from interfering with it) then the read request may become visible at least in your own Sent copy. That's not to say it will have any effect on whether or not Gmail presents the read receipt request to your correspondent.
Bear in mind that there is a part of an email message, its so-called envelope, that you don't get to see, and ISTR that some of the read reply business is transported in the envelope.
