Matt,

This whole area is covered by the SMTP protocol which defines the "conversation" that email servers have with each other when sending and receiving email. The relevant RFC (standard) is rfc 821 status error codes, google can point you to it. If you are coding at this level then it's pretty simple but I suspect this is not the case.

If you are trying to decipher these at a higher level e.g. php then things are more tricky and you need to start parsing the responses received (bounces) to look for the returned error messages. Unfortunately there is no standard for the response format and different mail servers have different formats so its always a best guess thing. The returned message SHOULD include the SMTP error codes which should help.
