i want to use the feature of generate work packages from mails in OpenProject 9.0.
I already edit the file /var/lib/univention-appcenter/apps/openproject/openproject.env so that i add the env variables IMAP_SSL, IMAP_PORT, IMAP_HOST, IMAP_USERNAME and IMAP_PASSWORD.
As it is shown here: https://www.openproject.org/operations/configuration/incoming-emails/
But there is nothing happening.
Maye someone can helb me? Maybe there is a logfile?
