What is the enhancement in mind? How should it look and feel?

I would love to have a mailbox history included in this addon, keeping track of sent mails (and perhaps also received).

Please provide any additional information below.

100% Agree. I actually came here trying to see if this addon did that very thing. Many times I've mailed something to someone and have it returned to me after 30 days and before I realize what it is, I've already opened it and didn't see who it was that I sent it to in the first place. It would be such a huge benefit to be able to go back and look at some sort of log or history of mail sent and received to see who I sent mail to, received it from or had it returned from, and what it contained.

Just had a similar use-case yesterday:

I shift-clicked Open All and then I saw that I received some gear from an unknown person. Only info I had was the mail subject ‘hi guildie’ in the console, but not the sender.

I know, it is my fault if I abuse the Shift-Open-All, and I also know that there is already a MailLogger add-on, but having a mini-log for, let’s say, the last 24 hours built into Postal would be a great feature.
