nobody reported imap problems
if users use both pop3 ( with stay mails on the server ) and imap
mails get to cur wtih seen flag ( as far i know by small tests ) if they
connect via imap
the problem users mostly use outlook 2010/2007 no webmail etc
and my test client is thunderbird ( current stable )
