v1.6.0

[1.6.0] - 2026-09-21

Added

• Headless CLI Real-Time File Logging & Export:
  • Added -l, --log <path> CLI option (with aliases --log-file, --export-log) to stream all progress logs, worker events, and summary statistics to a file in real-time.
  • Added LogFile <path> directive (with aliases Log, ExportLog) to ImapCopy.cfg for automatic logging when executing config-driven workflows.
  • Automated parent directory creation and auto-flushing to guarantee zero data loss during long migrations.
• Unsigned & Self-Signed SSL Certificate Bypass:
  • Added -k, --allow-invalid-certs, --insecure, --permit-unsigned-ssl CLI arguments to permit self-signed, expired, or internal SSL certificates in headless migrations.
  • Added AllowInvalidCertificates Yes (aliases: AllowInvalidCerts, PermitUnsignedSSL) configuration directive to ImapCopy.cfg.
• Headless System Sleep Prevention:
  • Integrated Windows power management (SetThreadExecutionState) into the CLI runner to prevent computers from sleeping during long unattended headless migrations.
• Modernized Default Template (Dist/ImapCopy.cfg):
  • Overhauled the default distributed starter configuration template with modern TLS 1.3 ports (993), SourceProtocol IMAP, Concurrency 4, AllowInvalidCertificates, and LogFile.
• Comprehensive Wiki & Documentation Suite:
  • Added 4 new dedicated guides for macOS (macOS-User-Guide.md), Modern OAuth2 (Modern-OAuth2-&-Cloud-Providers.md), Mailbox Quotas & Capacity Guard (Mailbox-Quotas-&-Capacity-Guard.md), and Live Logs (Logs-Search-&-Export.md).

v1.5.2

[1.5.2] - 2026-09-20

Added

• Dynamic Protocol Column Adaptation for Batch Migrations:
  • Added smart context-sensitive headers and badges for Microsoft 365 and Google Workspace in the Batch Account DataGrid (MainWindow.xaml and MainWindow.axaml).
  • When Microsoft 365 or Google Workspace is selected as Source or Destination:
    • Username header automatically updates to Source Mailbox (Email) / Dest Mailbox (Email).
    • Password header updates to Source Auth / Dest Auth and renders a clean 🔑 Admin OAuth2 badge.
    • Text editing is automatically disabled for password cells when passwordless admin authentication is active.
• Intelligent Multi-Format CSV and Clipboard Parser:
  • Re-architected CsvAccountParser with column header auto-detection (SourceUser, SourceEmail, DestUser, DestEmail, Password, etc.).
  • Added native support for 2-column email mapping CSVs (source@domain.com, dest@domain.com) without misidentifying destination email addresses as source passwords.
  • Added support for 1-column single mailbox lists (user@domain.com) commonly exported from Google Admin and M365 Admin centers.
  • Added protocol-aware parsing fallback to prioritize email-to-email mapping when source or destination protocols rely on tenant-level admin OAuth2 credentials.

Fixed

• Batch Migration Table Collapsing & Scroll Usability:
  • Fixed an issue where the Batch Migration accounts table collapsed into a thin line when empty or resized.
  • Wrapped the Batch tab in a responsive ScrollViewer and set a robust minimum height (MinHeight="280" container, MinHeight="276" DataGrid) ensuring all columns, headers, rows, and scrollbars remain accessible.

v1.5.1

[1.5.1] - 2026-09-20

Fixed

• Update Notification Button & ToolTip Theme Hardening:
  • Fixed button mouseover hover behavior, ensuring the update notification badge retains its dark emerald container (#047857) and bright neon border (#34D399) rather than falling back to Windows Aero light theme.
  • Replaced default system tooltip with a custom, dedicated dark-theme tooltip container (#0F172A, emerald accent border #10B981, drop shadow, crisp white title, and readable muted description) that completely eliminates unreadable white-on-white text.
  • Hardened global ToolTip template in App.xaml with OverridesDefaultStyle="True" and explicit foreground and typography bindings across the entire application.

Added

• macOS In-App Update Notification Badge:
  • Added in-app update notification badge to macOS header bar with 1-click navigation to the latest GitHub release and pointer-over styling.

v1.3.0

[1.3.0] - 2026-09-19

v1.1.0

[1.1.0] - 2026-09-17

Added

• Zero-Config Server Auto-Discovery:
  • Automatically resolves incoming IMAP host, port (993), and SSL encryption from any email address or domain.
  • Five-tier discovery cascade:
    1. Major Provider Directory: Instant mapping for Google Workspace, Microsoft 365, Outlook, Yahoo, iCloud, Fastmail, Zoho, GMX, Web.de, and Yandex.
    2. RFC 6186 DNS SRV Records: Queries _imaps._tcp (port 993) and _imap._tcp (port 143) to resolve corporate email endpoints.
    3. DNS MX Fingerprinting and Socket Handshakes: Identifies hosted enterprise services or probes custom mail exchange hosts via direct SSL handshakes.
    4. Mozilla Thunderbird ISPDB: Queries autoconfig.thunderbird.net for global ISP connection profiles.
    5. Domain Autoconfig XML: Probes standard hosting control panel endpoints (cPanel, Plesk, DirectAdmin).
  • Strict Verification: Prevents unwarranted assumptions; unverified domains remain blank for explicit manual configuration.
  • Interactive UI controls: Added Auto-Detect buttons for source and destination hosts across Single and Batch tabs.
  • Reactive input: Initiates discovery when a valid email address is entered into an empty server field.
• In-Flight Account Queueing and Dynamic Batch Execution:
  • Allows adding accounts to an active batch migration without stopping or restarting the running process.
  • Individual row controls to immediately queue newly added accounts into the running execution stream.
  • Dynamic queueing support for clipboard paste and CSV file imports during an active run.

  • Universal dark alert dialogs: Integrated DarkMessageBox across the application, removing standard Win32 prompt dialogs.
• Multi-Tier Message Deduplication Engine:
  • Prevents duplicate message transfers during incremental runs when headers differ across IMAP implementations.
  • Three-tier identification hierarchy:
    1. Normalized RFC 5322 Message-ID: Trims enclosing brackets, strips whitespace, and performs case-insensitive comparisons.
    2. Composite Fallback Fingerprinting: Generates a deterministic signature using UTC timestamp, sender address, and subject line when Message-ID is missing or returned as NIL.
    3. Synthetic Message-ID Injection: Generates and embeds a deterministic synthetic header (<synth-{hash}@mundofy.migrated>) into the destination message when transferring messages that lack RFC Message-IDs, ensuring subsequent synchronization passes detect existing items immediately.
  • Unified across IMAP and POP3 migration engines.
  • Diagnostic logging of message subject, timestamp, and identifier per transferred item.
