Ok, I got it working with LAYOUT=index

 

If I manually create the homedir then it works as expected

 

I’ll go ahead and re-import my data – thank you.

 

Not sure if the behavior I described so far is a bug and if I should file it as such (?)

 

Thanks once again

You could test this out first on your test deployment. index layout is pretty permissive as it uses guids instead of names on disk.

Like this ?

 

mail_location = maildir:/ssd_bkp/ingestmail/mail/%n@%d:BROKENCHAR=_

 

still throws the same error

 

I could try migrating to a new layout but will it fix the issue ? I already imported about 250GB of data which I assume I have to throw away and start over ?

 

Is this a bug in the listescape plugin ?

Thank you for your assistance

You could try adding :BROKENCHAR=^

 

to mail location, or you could migrate to LAYOUT=index.

I see the plugin being loaded when the imap session starts

Is this possible at all ?

 

I am trying to import a PST file and it has a slash in the folder name.

Dovecot errors out with :

 

APPEND "Caixa de Entrada_VIDA/S1" (\Seen)

NO [CANNOT] Invalid mailbox name: Name must not have '/' characters

 

My namespace separator is the dot and I configured the listescape plugin to

escape / but it still doesn't work.

 

The listescape documentation says:

 

The / character is disallowed on POSIX systems.

 

This plugin allows you to use all of these characters, as long as the

virtual separator (i.e. what is set by the separator setting and used as

such by the IMAP protocol) is changed to something else, which means that

the plugin does not make it possible to use the virtual separator in folder

names.

 

 

So it seems that as long as I use the dot, it should work ? Except it

doesn't...

 

How can I do this import ?

 

Thank you!

Should work by just loading listescape plugin and not using / as namespace separator.
