I've done further investigations... keeping kmail closed and akonadi 
stopped, I retrieved new mails on Thunderbird and read those.
Back to Kmail, checked new mail... they are correctly marked as read!

So the issue seems to be limited to mails that are already fetched by 
Kmail and later read on other clients. For those mails already marked as 
read, KMail seems to retrieve the correct status.

Odd...
