[Evolution] Mark emails as read annoyance

[Ralf Mardorf <ralf mardorf rocketmail com>]

Hi,

is there a way to prevent Evolution from marking Emails as read, after
switching from one folder to another only?

Evolution should mark mails as read after a while, but not after
switching from one to another folder, they should be marked as read
after a while only, if I switch from one mail to another inside a
folder.

Regards,
Ralf
