Hi marc,

so is this a question from your side?

Please post your config here with dovecot -n in case you need support from my side. I got it working with a flat hierarchy :)

Kind Regards, Christian

Hi Christian, nice you got this. I could have given you this also, but I have this weird tree in the mail client, so I thought better not share it. I prefer to see only 1 'Archive'

...

I found the Solution myself. The key was to simply create an unnamed mailbox directive so that the namespace prefix directly results into an mailbox that Thunderbirds shows as the Archive.

Thanks everbody on the dovecot team for making such a brilliant Software! Greetings! Christian

namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / }

namespace archivns { prefix = Archive/ <--- this is the Name which now appears at the same Level then Sent/Draft/... location = maildir:/mnt/mails2/%u separator = / mailbox { <--- here a name is omitted auto = subscribe special_use = \Archive } }
