- Settings > Backup & reset gets a Mail files section for Import mail and Export all mail, instead of sitting under settings backup. - The pause message names Stalwart's 50000000-byte quota as 50 MB, not 48 MB, and the dialog and settings texts mention .ost files. - The old import's leftovers go: expandImportableEmails and EML_IMPORT_ACCEPT in lib/eml-import.ts, and the strings email_viewer.import_email, mailbox_context_menu.import_email and notifications.import_email_success/_error in all 30 locales. lib/__tests__/eml-import.test.ts loses the tests of the removed functions; its #891 checks that an .eml and an .eml in a ZIP keep their Date header now run against the import's own sources.
