I have the same problem: There is no option to mark messages as seen within
filters. But I'm not using the maildrop driver but procmail.
I could not find out whether the procmail driver supports this, but I found out
that procmail can, so I thought there shouldn't be a problem to have the driver
doing this.

The following page describes how procmail can mark messages as seen:

Any hint?
