I?m trying to configure dovecot to use mailbox subfolders that look like both
foo/bar on the IMAP client and the filesystem.
But the subfolders created all look like foo.bar, not foo/bar with a proper
nesting structure.
This also happens when the folder ?bar? is moved into the folder ?foo??A new
folder `foo.bar? is created.
I believe that i?m following the configuration rules at
https://wiki.dovecot.org/MailboxFormat/Maildir#Maildir_and_filesystems and
https://wiki.dovecot.org/MailLocation/Maildir. This issue happens whether I set
separator to its default, ?.?, or ?/?:
> mail_location =
mdbox:/private/var/mail/tld.hostname.mail/%Ln/mdbox:LAYOUT=fs
> namespace inbox {
> ?
> separator = /
> ?
> }
The IMAP client is macOS Mail.app version 14.0.
I?d greatly appreciate any help or pointers to fix this configuration issue.
