Subfolder in sieve not working as expected
Hi everybody,
I am trying to move incoming mails into subfolders with this sieve script:
require ["fileinto", "variables", "mailbox"];
if header :matches "Delivered-To" "*@*" { fileinto :create "INBOX/${2}"; }
On a message to user@example.com I would expect it to be stored in the folder 'example.com' under 'INBOX', but instead a folder named 'INBOX\2fexample.com' is created. I tried several options:
- replace / with \/ or \\/
- replace / with .
- disable listescape in dovecot.conf Unfortunately nothing did the trick. Any ideas what could fix this?

I am not using variables and my folders are pre-created. But just to give you a starting point, this is what works using maildir++ format with default directory layout. https://doc.dovecot.org/configuration_manual/mail_location/Maildir/

ok, I am trying to start simple:
removed the mail_plugin "listescape"
set mail_location = maildir:%h/%d/%n/Maildir
and changed the sieve script into:
require ["fileinto", "variables", "mailbox"];
if header :contains "Delivered-To" "@example.com" { fileinto :create "INBOX.example"; }
Running sieve from the cmdline returns:
error: msgid=<76c62f93-527a-d8d9-f787-65926d9c3e25@domain.com>: fileinto action: failed to store into mailbox 'INBOX.example': Character not allowed in mailbox name: '.'. sieve-filter(vmail): Info: sieve: msgid=<76c62f93-527a-d8d9-f787-65926d9c3e25@domain.com>: left message in mailbox 'INBOX'
For some reason the :create seems to have a problem with the folder separator '.'
Any clue how to get '.example' recognized as a subfolder?

In your previous email, you wrote:
separator = ~
You might want to change that to:
separator =
(Which defaults to a dot as mailbox separator)

It is indeed the separator, thanks Remy! The confusion came from the different kind of separators defined in multiple places and also used in different places.
To summarize:
Each namespace defines a separator, but you must use the same in all namespaces (why isn't this a global setting?).
Each LAYOUT="<x>" has an implied separator on its storage. Maildir++ uses the dot, "fs" uses slash., this is the separator visible on the filesystem.
IMAP has a separator on the wire, which then translates to the LAYOUT separator on the filesystem.
Separator conflicts between imap and layout separator can be avoided with the listescape plugin
To use a dot or a slash in folder names neither one should be used as the namespace separator.
To have IMAP folders stored in a filesystem hierarchy of subdirectories LAYOUT=fs should be used.
As it turns out the namespace separator is the one to be used in sieve scripts, whereas I actually used the LAYOUT separator.
In any case where to use what separator was not immediately clear to me. The sieve docs and examples on wiki/doc site do not mention the namespace separator at all. It would be helpful to put a remark or pointer there. But now it works (famous last words) :-), thanks again.
