Latest Updates
View all releases- Mailing Lists — Grid View Action Buttons Unresponsive:
- Fixed all action buttons (Subscribers, Create Message, Edit, Clone, Delete) on mailing list cards being unclickable. Root cause: the list name <Link> contained a <span class="absolute inset-0"> overlay that covered the entire card (which has position: relative), intercepting all click events and redirecting to the edit page. Added relative z-10 to the action buttons container to elevate them above the overlay.
- Tailwind CSS v3 → v4 Migration:
- Migrated from Tailwind CSS v3 to v4 with new CSS-native configuration approach.
- Replaced @tailwind base/components/utilities directives with @import "tailwindcss" in app.css.
- Added @custom-variant dark (&:where(.dark, .dark *)) to preserve class-based dark mode toggling (replaces darkMode: 'class' from tailwind.config.js).
- Added @theme block with font-family configuration (replaces theme.extend from tailwind.config.js).
- Converted @layer utilities custom classes to @utility syntax.
- Mailbox Reputation — False Blacklist Positives:
- Fixed all mailboxes being incorrectly flagged as "Na czarnej liście!" (Blacklisted). Root cause: Spamhaus, SURBL, and URIBL return special error IPs (e.g., 127.255.255.254) when queried from public/shared DNS resolvers (Google DNS, Cloudflare). The checkDomainDnsbl() method treated any DNS response as "listed". Now validates response IPs and filters out known error/block/test ranges before determining listing status.
- Migration resets all existing reputation data so the corrected logic can re-evaluate on next check.
- Mailbox Reputation — "Error checking reputation" Button Failure:
- Fixed the "Check Reputation" button in Mailbox settings returning an error. Root cause: frontend called route("mailboxes.check-reputation") but the actual route name is settings.mailboxes.check-reputation (due to the Route::prefix('settings/mailboxes')->name('settings.mailboxes.') group). Updated Mailboxes/Index.vue to use the correct route name.
