Could recoder subject on tracking?

[akong]

Hello,
I know tracking center is get mail.log this file to show it. But I hope it's also show mail subject on tracking center. Could support it in the feature?

The subject is a rather sensitive part of a mail - While the (envelop) from and to addresses are necessary for debugging, the subject is not needed.
Therefore I would not add it to the logs
