[ Centos ] Postfix dsn status script

Centos postfix DSN translation script - tells you what your mail is doing. In case you have no clue what we are chatting about view your maillog/mail.log :

Oct 1 00:35:01 ghosting postfix/smtp[1437]: ABA987666094: to=, relay=gmail-smtp-in.l.google.com[209.85.222.73]:25, delay=9881, delays=9880/0.01/0.22/0.71, dsn=2.0.0, status=sent (250 2.0.0 OK 1254342900 5si70217753pzk.88)

This largely tells you what has been done with your mail when the "status=xxxxxx" line or the message of why your mail fails is "vague".
