Please note that addition of Gmail Label/removal of Gmail Label at Gmail's Web Interface is possible on "Conversation" only. Show conversation in which one of member mails has Gmail Label of XXX. Gmail's logic to "show mails labeled XXX" at Web Interface seems Gmail's mail showing at Web Interface looks "Conversation basis", intead of "mail basis". If "Expand All" is requested, "Mail before attachment deleted"(UID=MM) and "Mail after attachment delete"(UID=NN) are shown in a conversation.Ībove is same even after "removal of Gmail Label of B from mail of UID=MM by Compact=expunge at folder B via IMAP".

By expunge, Gmail Label of B is removed from mail of "UID=MM in All Mail".Īt Gmail Web Interface, UID=MM(has Gmail Label of "B") and UID=NN(has Gmail Label of "B") are shown as single conversation(the conversation contains 2 mails).Īnd, as "Mail before attachment delete"(UID=MM) was uploaded to or arrived at Gmail earlier, older "Mail before attachment delete"(UID=MM) is shown. The UID=2 is removed from folder B by "Compact"(expunge is requested). are same) except different headers and data in some parts under multipart/mixed.Īt folder B, "Mail before attachment delete"(UID=2) is kept with \Deleted flag as expected with auto-expunge=Off. Gmail kept two mails of same mail headers(message-id, subject, from. UID=NN : Original mail of UID=8 in folder B (single copy of a mail) UID=MM : Original mail of UID=2 in folder B (single copy of a mail) UID=8 : Attachment part is text/x-moz-deleted, as expected. UID=2 : Shown with strike-thru line, with trash can icon (\Deleted is kept) Tb appeded new version(UID=8), stored required flags to UID=8, then stored \Deleted flag to old version(UID=2), as expected. This happened with several e-mails, and I only realized it was happening when I saw my "Using x MB of your y MB" increasing in Gmail's web interface WHILE I was deleting attachments in Thunderbird, even though I wasn't receiving any new messages.įollowing is IMAP log with Tb 6.0 when "delete of attachment" is executed on mail of UID=2 which has flag of "$label4"(To Do) and "nonjunk.įor ease of testing, Gmail IMAP's auto-expunge option is disabled and Tb's delete model of "Just mark it as deleted" is selected. No duplicate e-mails or attachments, just the one e-mail with no attachments. A duplicate of the original e-mail, with all the attachments intact (see screenshot) The original e-mail, with a list of attachments that said "deleted: (filenames of attachment)"Ģ. BUT when I checked the messages again via Gmail's web interface, it showed:ġ. Thunderbird showed that the attachments were deleted. Clicked OK when the "cannot be undone" prompt was displayed. Selected a message, went to the attachments, and selected "delete all.".ģ.
