Description

Hi,

my problem is that the mails are not deleted from the trash, they are just no longer displayed.

Steps to reproduce

I use PEP for Android as client. When I look at sogo, I no longer see any mails in the trash, but hundreds can still be seen on the admin page. Only if I click on empty recycle bin again via sogo, then they are gone.

I have the same behavior with Thunderbird. If I delete them one by one, the mails are only set to not visible, only by empty recycle bin they are really gone. It looks like the expunge: box=Trash step is missing when deleting it one by one.

How can that be changed if I don't always want to login with sogo or thunderbird to finally delete it? I don't want to empty the trash after X weeks, only manually.
