Which is best Postfix Log analyzer?

Question

Which is best Postfix Log analyzer? We are looking for good log analyzer for postfix. We need to analyze the following

1. How many mails queued ?
2. How many mails not delivered ?
3. Why mails are not delivered ?

And is it possible to view the subject for the all mail status instead of message id? I mean to review the status of the single mail.

We are using Sawmill analyzer now. But the management is not satisfied with the report from the sawmaill, since its missing single message status and subject.
