I need to cathegorize bounced mails using JavaMail into three cathegories: hard-bounced, soft-bounced and full mailbox. At the beginning, I used the reply codes defined in rfc 821 to distinguish between bounced mails, e.g: 550 for soft-bounce, 552 for full mailbox, etc. But later I found out that this reply codes are not adopted properly by some mail servers. Under same condition different mail servers could return different reply codes as well. Some mail servers don't even returned reply codes! They gave a short description instead.

Is there any general way to accomplish this task? I thank in advance.
