Mine looks like this:
     if anyof (header :contains "sender" "@dovecot.org",
header :contains "to" "redacted at example.com")
     {
         fileinto "INBOX.Dovecot";
     }


I notice your rule has ":create" which might be why its always
creating a new folder.
Try the rule without the ":create"

Hi!

See here for the relevant stuff.
Basically you haven' passed "LAYOUT=fs" to mail_location
So you need to use "." for hierarchical separator.

I presume there IS some advantage for the default Maildir++ format, but I
don't know what that is...
