Add option to auto-complete email addresses from history of senders
It seems from the documentation that Airmail will happily suggest address I've emailed in the past from Airmail. However it won't look through my IMAP history and suggest people who've emailed me, or even through my sent messages folder to suggest addresses I've emailed in the past using a different Mail client. We haven't all been using Airmail forever! (I know that I should probably put some of these into my address book, but this probably won't happen for everyone). It turns out that I rely on this feature in Mail.app quite a a bit.
This app would be perfect if this feature was working

I don't know why, but from the version 3, the app stop auto complete emails from past messages, I need to add every person in order to don't need to remember or retype every single time.
PLEASE, put that thing to works ASAP as it used to be.
