Every release, newest first. Mailcellar updates itself — or choose Check for Updates… in the Mailcellar menu.
Mailcellar 1.2.0 Latest
NewConnect in a minute: Gmail, Outlook.com, iCloud Mail and Fastmail presets show plain steps and link straight to the page where you make an app password.
NewPreview Backup: before anything downloads, see how many messages, how much space and which years the first backup would save, and whether it fits on your Mac.
NewImport Apple Mail exports (the .mbox folders from Mailbox › Export Mailbox…), whole folders of .eml or .emlx files, and mbox files without an extension. You can drop them on the window, and importing the same mail twice adds nothing.
NewThe welcome's last page lets you pick your provider and go straight to signing in.
ImprovedFree Up Space says more clearly what stays the same: your vault copies are never touched, and steps 1 and 2 only read. A "Look at the copies first" link shows the verified files in Finder before you release.
ImprovedThe import shows its progress in the sidebar, and you can stop it.
FixedSwitching views no longer flashes the previous message in the reader for a moment. Messages you opened recently now open instantly.
FixedAn address that belongs to another provider (say, an @icloud.com address under Outlook) now offers to switch to the right settings.
Mailcellar 1.1.0
NewThe vault — a timeline of your years of mail and a “Verified copy” seal on every message.
NewFree Up Space removes mail from the server only after every copy is verified, confirmed by typing RELEASE.
FixedA copy could be overwritten by a different message of the same size; duplicates after a server renumbered a folder.
ChangedMailcellar now asks for your license key on first launch — there's no free trial.
