special-use for virtual folder

Hi,

I'm running two different Dovecot servers (actually more but those are pretty similar and same versions 2.2.24).

Today I configured a virtual All folder on both:

namespace { location = virtual:/etc/dovecot/virtual:INDEX=~/virtual prefix = virtual. separator = . }

mailbox virtual.All { special_use = \All }

On this system the special-use flag is not applied to the folder (checked via LIST "" "*").

On the other system: namespace { location = virtual:/etc/dovecot/virtual:INDEX=~/virtual prefix = virtual/ separator = / } mailbox virtual/All { special_use = \All }

On the second system I can see

• LIST (\HasNoChildren \All) "/" virtual/All

Besides the separator I don't see a big difference between both configurations.

Any idea?

Thanks, Wolfgang
