Mapping the Exchange/Kerio special folders onto mailcow's by hand is repetitive work that scales with the number of accounts. "By default" maps Deleted Items to Trash, Junk E-mail to Junk, Sent Items to Sent and unchecks Public Folders, which mailcow has no counterpart for. The destination select only offered the source folder as a name to create, so a target missing on the destination could not be selected at all. It now also offers the current selection, and marks any name absent from the destination as "(create)". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
