syslog msg: Option 'flushseenstate' is deprecated in version 2.5.0.

[Matthias Busch]

Kolab 3.4 (upgrade from 3.3) on Debian 7.8 x64


Every few minutes I get a

kolab imap[31423]: Option 'flushseenstate' is deprecated in version 2.5.0.

in syslog.

Seems to be not critical. Possibly something that needs to be addressed 
by devs?
Diddnt find anything in the list of bugs, google hits are none kolab 
related.

If I can "fix" it with config settings I'd like to know how.

thanks...
