Actual results: Thunderbird sends a new receipts Expected results: Since the mails are already marked as read, TB should not send another receipt
Is this with Thunderbird 52? ref bug 1321219
yes and 4x
(In reply to Kire Dyfvelsten from comment #0) > Since the mails are already marked as read, TB should not send another > receipt I don't think this expectation is right. If the sender requested a receipt, TB will prompt or send the receipt regardless of whether the e-mail was read.
Windows Live Mail or Outlook has allready sent an receipt for those messages, i dont know if there is something else one could look at, else than the read flag... Many of our users has several years old imap folders.. and they sometimes have to re-read a message later. and that should not trigger a new receipt. A "workoround" could be that it only sends reciepts from the inbox folder?
Joe do you have experience in this area?
My main "work" email is pop3, and the occasional request for receipt seems to work fine.
