Would it be possible to add the option to print mail contents/sales/bids/gold to the chat box in a similar to retail TSM.
This makes it easier to quickly view the result of your auctions & bids, especially effective when using an "open all " addon to open a large amount of mail

I've included an example screenshot.

No. No point in adding this to aux as there is no connection to the ah, it's purely a mail addon.

That is a fair point.
You also develop Mail, would it be more suitable to repost this suggestion there or is the answer the same?

It's more suitable but I'm not interested.

Understood, thanks for your response.
