I will move to Airmail if 1) move folder between local mailboxes 2) export all emails to mbox format in case of need of change client
1) need to move folder between local mailboxes - it's crucial. Outlook, Thuderbird have it, why AirMail doesn't?
2) In case of need of change mail client I'd like to export all my e-mails with folders from local mailbox to any mbox format, etc. Why it is not there, while all other mail clients have it?
I've had this concern since 2016 as well. It's one of the reasons why I stopped using Airmail. I would use it again if this changed.
