QuickMail v0.6.1 Release Notes

Released May 23, 2026 — downloads for this release

New Features

IMAP IDLE — real-time new mail notification

QuickMail now uses IMAP IDLE to detect new mail as soon as it arrives, without polling. After connecting, a dedicated background connection per account watches the INBOX. When the server signals that a new message has arrived, QuickMail runs a targeted sync for that inbox and the message appears in your list automatically — no manual refresh needed.

Online mode (--online)

A new --online command-line flag runs QuickMail in fully live mode: every folder selection fetches messages directly from IMAP, and nothing is read from or written to the local SQLite cache. Useful for a clean look at your mail without any cached state.

QuickMail.exe --online

12-hour clock and updated date format

Message dates in the list now use a 12-hour clock with an A or P suffix for today’s messages (e.g., 9:30A, 3:45P), and M/d/yyyy for older messages (e.g., 5/22/2026).

Bug Fixes

• IDLE push not working in --online mode — The IDLE watcher was never started when --online was active, so new mail required a manual refresh. IDLE connections now start regardless of caching mode, and new arrivals are fetched live from IMAP and merged into the message list without touching the cache.
• Delete and Move to Folder crashing in --online mode — After a successful IMAP delete or move, QuickMail tried to remove the message from the local SQLite cache, which doesn’t exist in online mode. This produced the error “SQLite Error 1: no such table: MessageSummary”. Both operations now skip the cache cleanup step when running in online mode.
• Preview text showing when Preview Lines is set to 0 — When PreviewLines = 0 in Settings, the IMAP PREVIEW extension on the server was still populating preview text in the message list. QuickMail now clears preview text when loading or inserting messages whenever the preview display is disabled.
• Preview Lines 1–5 all showing the same amount of text — Because IMAP PREVIEW strings from the server contain no newlines, the line-splitting logic treated any value 1–5 identically. Preview text is now capped at 100 characters per line (100–500 characters for settings 1–5), giving meaningful control over how much preview text is announced.

Internal

• Added SyncOneFolderOnlineAsync to ISyncService / SyncService for IDLE-triggered inbox refreshes that bypass the local store.
• Added SessionFeaturesTests.cs with 12 new tests covering date display format, preview suppression, the OnlineMode constructor flag, and IDLE-triggered sync dispatch in both normal and online modes.
• Total test count: 223 (v0.6) → 235 (v0.6.1).
