Hi Kostya,
When long pressing the [Deleted] folder, it shows
--> junkmail
Which I'm guessing means it's syncing to that folder?
I have another program (Pop Peeper) monitoring the mailbox, and the message disappears from the inbox when deleted, and returns when restored.
Actually, this time it worked as expected, and the message wasn't purged.
I've just tried it again, deleting two messages, and restoring the second deleted message, and that hasn't been restored to the inbox, and has been purged along with the other deleted message. (Which is the bug)
All the previous times I've seen the buggy behaviour, have been when I've deleted >1 message, and the restored message has been purged along with the deleted messages. I'll try another couple of tests and see if I can narrow it down further. I suspect that I need to have a deleted message remaining to trigger the purge process.
Don.
