Our Dovecot installation is configured as such:
mail_location = mbox:/var/vmail/%u:DIRNAME=.mboxdata:INBOX=/var/vmail/%u/INBOX:INDEX=/var/vmail/indexes/%u
This allows us to continue using mbox formatted files, storing those mbox data files in a file called .mboxdata. This allows our users to create folders and subfolders. The only exception to this is our inboxes, which are more traditional mbox files.
However, we have some Outlook users that insist on trying to create subfolders of their inbox. This doesn't work, since the inbox is a file. But Outlook still does it and it causes sync issues, as there is now a subfolder under the user's inbox, but that subfolder is ONLY present in Outlook (it isn't present on the server).
Is there anything that we can configure so that Dovecot instructs Outlook that it cannot attempt to create subfolders under the inbox, but allow subfolders elsewhere?
Thanks! Bryan
