I'm trying to automate the processing of returned emails (mailbox doesn't exists, box full, email rejected (as spam / sender blacklisted etc)). Looking at returned email from yahoo and hotmail, they seem to have the field "Diagnostic-Code" which seems like the field I should process. Do all mail systems return this field? Are there any other fields included in the returned email that are universal... that i can use to process returned email?

Answer to that would "no".
The only required fields are those in the RFC for SMTP, and most of that can be faked.

There are various standards in returning mail, some just use the numeric code, others use different text for the same return, some give no information at all. Very difficult to decode, even visually, and I run many mail servers.
