About the message-id, yes it should be global unique and it "should" be in every message. See the rfc for more details: http://www.faqs.org/rfcs/rfc2822.html <- 3.6.4. Identification fields So you could try to check for the message-id and if you received the message already just set the state of the message to Mail.GHOST. An other idea would be to generate a md5 of the message and check if you have a match..
