Password protected inbox
I have kids, and i get mails that i want to "hide" from the kids and anyone else that i don't want to read my private mails, lets say from my lawyer. I would love to see a feature where you can password protect the whole app or just the inboxes, like i could chose to keep my iCloud inbox "open" but my Outlook inbox password protected. Been searching for mail clients that can do this but no success so far.
Me too for this feature...
Looking for the same feature
You can actually do this with Postbox application for MacOS. This was one of the most important features for me that is why I did not choose Airmail for my business mail application. Combining password protection with an inbox located in encrypted volume/container is elementary for business users that care about data privacy.
