I seem to recall that, while utilizing Claws Mail (3.7.5, if I recall correctly) on Ubuntu, deleting mail on an IMAP server sent it to the trash and set the IMAP deleted flag. This would result in having to expunge both the folder it was in, and delete and expunge it from the trash. To me, this was the wanted behaviour. This does not seem to be the case at the present time using the current Win32 version. In this case, deleting does not move to trash in any case (even if I've set the folder information in Preferences For Current Account > Advanced) and only sets the delete flag. Can anyone else confirm this behaviour?
Yeah, I think it was working as you describe for me (gentoo) in 3.7.2. I missed some updates that weren't packaged, so IDK when the behavior changed, but it doesn't seem to work right for me on 3.7.5. I agree that it should mark them deleted and -- now IDK if "move them to trash" is actually what is *supposed* to happen (and could explain the change) but, perhaps a settings flag to show/not show "deleted-not-expunged" messages is preferable. This way seems more in line with what I recall, FWIW. ;-/ I suppose it'd be possible to implement like this... surely an option can be added to the global config for IMAP so either a deleted message gets displayed on folder display, or not. As done that way, you'd have the option to handle usefully, w/o losing information (the originating folder that is), all the deleted -- but not expunged -- messages..?? There, my $0.02USD. Hope it's a help.
That would probably be the ideal solution, one I think that may have been proposed before. I don't want deleted messages cluttering up my inbox, but also like to be able to undelete if necessary. Having an option to hide expunged messages would be excellent.
I can't reproduce that. When moved to trash, the email is copied to trash, flag \Deleted set on the original and then expunge is done (or not depending on the Immediate Execution preference). But, there is now Move to Trash which does what you want, and Delete, which does not put anything in Trash. Maybe that's what confused you? comment #2: there is such an option now.
