Hi,
I'm trying to workaround the lack of IMAP folder mapping settings on Windows 10 Mobile in regards to controlling the Sent, Trash etc folder my device uses. Currently, my device creates its own "Sent Items" folder "Deleted Items" folder along with others, this is pain when using clients like Thunderbird which places such them in the correct places, because it can be configured this way.
While this is a Microsoft issue, its looking very unlikely they will add IMAP mapping control, as its been like this since Windows Phone 7. So I was looking for performing a workaround at the server level.
I came across the Dovecot Mailbox alias plugin, which sounds like a decent workaround, to at least allow sent email messages from my Windows 10 mobile device to show up in the right place, I'm aware of the potential for double cache etc, but I have enough storage for it.

What I'm having difficulty with, is expressing the mailbox_alias to an existing INBOX. folder. My email server uses the INBOX prefix setup, so my configured folders are:
INBOX\INBOX.Sent INBOX\INBOX.Drafts INBOX\INBOX.Trash INBOX\INBOX.Spam
Most examples seem to indicate doing at the root folder level i.e. Sent Items -> Sent not Sent Items -> INBOX\INBOX.Sent.
Is it possible to use the alias plugin in this way? If so how would I express this using mailbox_alias_old, I tried INBOX/Sent, but this seems to send all items to a blackhole, as they can no longer be found in any folder.
It does appear to work at the root folder level, but as my setup is using the older INBOX prefix, I don't want to do that.
Any hints/tips would be appreciated!
Thanks,
James
