java - JavaMail - Stop automatically sending read receipts -


i'm developing mail client (imap/smtp) javamail. client talk exchange 2010 server automatically sends read receipts when set flag seen in messages require them. how can avoid server send these receipts? tried remove disposition-notification-to header messages following exception:

javax.mail.illegalwriteexception: "imapmessage read-only"

even if open folder in read_write mode. read problem due imap protocol limitation. there way not send read receipts?

you can't in client. client doesn't it, , imap offers no way configure exchange.

(also, imap offers no way modify messages. once stored, message can cached forever client , not modified other client.)
