Error: Virtual mailbox loops, Dovecot version 2.2.10
I'm trying to follow the guide at https://wiki.dovecot.org/Plugins/Virtual for the 'Conversation' style virtual mailbox, but with a small change. I'd like the virtual mailboxes to be 'top level', which I found while searching through this list is accomplishable by putting the dovecot-virtual file in the root of the namespace location. My issue is this works perfectly fine for the All Mail virtual mailbox, but the Threaded mailbox fails with the error above. I tried creating a RealMail namespace, but that doesn't solve the issue either. I feel like I must be overlooking something simple; I could get this setup working if the virtual mailboxes shared a namespace and were subfolders, but I don't like that setup much (I'm trying to get my companies GMail users on to our own webmail client, it's features like this that I need to replicate with dovecot or they'll never leave their POP3 setups).
I've attached the output of dovecot -n, and my virtual mailboxes look like this:
# cat Threaded/dovecot-virtual All inthread refs x-mailbox INBOX
# cat all/dovecot-virtual RealMail RealMail/* -RealMail/Trash -RealMail/Trash/* -RealMail/Spam -RealMail/Spam/* all
I'd appreciate any insight in to this issue. If I try to access the Threaded Inbox through IMAP, I get this error specifically: a select "Threaded Inbox" a NO [SERVERBUG] Virtual mailbox open failed because of mailbox All: Internal error occurred. Refer to server log for more information. [2017-04-03 00:24:28]
The relevant line being: Apr 3 00:24:28 mail dovecot: imap(dan@redchops.com): Error: Virtual mailbox loops: No information before or after.
Thanks, -Dan

Actually, I ended up figuring it out. I removed the RealMail virtual changing all to just select all from *, set the all mail virtual to 'hidden=yes, list=no' and left the threaded virtual alone and it worked.
Unrelated to this, but since I wanted these folders to be top level, and thus they're empty namespaces, setting hidden=yes, list=yes on the threaded virtual allowed it to work correctly with Thunderbird. Without hidden=yes, Thunderbird complained that the folder didn't exist.
I hope this helps others,
Dan
