I understand that seen messages must be moved to 'cur' folder. My 
question is: when web mail client lists messages in front page, none of 
them selected yet, do they become SEEN or not?
The second question: if I disable pop3 with XMail and use dovecot for 
pop3 service, can I see emails in 'cur' folder via pop3 connection?

Thank you,
