The system is a Centos 7.3 with Kolab 16
rpm -qv pykolab
pykolab-0.8.7-1.3.el7.kolab_16.noarch
rpm -qv kolab
kolab-16.0.1-8.1.el7.kolab_16.x86_64
I made several EML files and imported them via the webmail interface of Kolab. The mails look fine, except for the column date in the view it is empty. The date is also not shown in the mail when you open it in Kolab. This column is empty. When I open the exact same EML file in Thunderbird, the date and time is shown in both the view as the e-mail itself.
I expect the date/time information to be displayed in both the view as in the mail itself.
