+- 优化登录与会话流程：登录后完整返回原页面及查询条件，区分未登录、超时、取消和网络故障，并为服务不可用状态提供明确的重新连接入口。
+- 完善后台与邮箱错误处理：管理员设置、邮件列表、邮件详情、发送队列、个人资料、签名、DNS 检查及注册流程均增加真实失败提示和重试反馈，避免静默失败或错误成功提示。
+- 优化邮箱与个人设置：恢复显示名称编辑，新增可持久化的标准/紧凑邮件布局，移除无效时区和模拟资料，修正发信成功后草稿删除失败的提示逻辑。
+- 保持并强化转发规则：账号级转发目标在所有邮箱中默认勾选、置顶且不可取消，单邮箱可继续追加独立目标，现有单邮箱配置不受影响，目标按数字和字母排序。
+- 统一界面视觉与交互：采用更清晰的中性色、文字层级、焦点状态和紧凑圆角，补充图标按钮名称、工具提示及全屏页面主区域，改善桌面与移动端可访问性。
+- 优化前端加载与开发体验：拆分邮件编辑器相关代码包，控制单个构建文件体积，并支持通过 `VITE_API_TARGET` 指定本地后端代理地址。
+- 加固邮件 HTML 安全：升级 DOMPurify 至已修复版本，依赖审计无已知漏洞；同步清理过时演示数据、无效状态和旧页面逻辑。
+- 完成全量质量复核：前后端构建、Go 全量及竞态测试、SMTP、外部 IMAP、OAuth、Telegram、Webhook、转发、队列、权限隔离、安装、备份、回滚和 DKIM 同步测试均已通过。

+- 修复 QQ 邮箱、网易邮箱、Gmail 等第三方客户端可以收信但无法发信的问题。
+- SMTP 提交服务新增 `AUTH LOGIN` 认证支持，并继续兼容 `AUTH PLAIN`；两种方式均只允许在 TLS 加密连接中使用。
+- 兼容带初始用户名和标准两步用户名/密码挑战的 LOGIN 流程，适配常见手机邮箱、Apple Mail 和 Thunderbird。
+- 客户端配置保持 IMAP 993/SSL、POP3 995/SSL、SMTP 465/SSL，不增加额外服务器地址或备用配置。
+- 新增 SMTP 能力声明、LOGIN 认证、STARTTLS、隐式 TLS 和完整发信回归测试。

+- 优化转发验证完成页：移除“返回邮箱”入口，外部收件人确认 Netflix、ChatGPT 等验证码转发授权后不会进入邮箱登录页，只显示验证结果和关闭页面提示。
+- 合并验证邮箱搜索与添加入口：输入内容会实时筛选已添加地址，输入新邮箱时可直接发送验证邮件，已存在地址会明确显示为“已添加”。
+- 重整验证邮箱管理列表：待验证邮箱置顶展示，已验证邮箱按数字和字母排序并聚合为可折叠分组，邮箱数量较多时仍便于查找和管理。
+- 精简邮件转发主页面：不再平铺全部验证邮箱标签，改为显示已验证与待验证数量汇总，点击即可进入管理列表。
+- 补充验证完成页回归测试，确保页面不再出现邮箱首页或登录入口，并完成前端构建、组件规范、后端全量测试与静态检查。

+- 修复收信规则移动到自定义文件夹时被错误归入“已归档”的问题，现在会按规则名称真实创建目标文件夹。
+- 修正发件人、附件名、邮件大小和日期条件的匹配边界，拒绝字段不支持的运算符，避免规则保存后永远无法命中。
+- “应用到现有邮件”不再处理已发送和草稿邮件，规则暂停启用时也可执行用户明确选择的现有邮件处理。
+- 完善规则动作失败处理：失败的动作不再误中止后续规则，归档、删除和移动错误不再被静默忽略。
+- 收信规则列表新增适用邮箱显示，并提供独立的上移、下移按钮，多条规则时可完整调整优先级。
+- 新增自定义文件夹图标，支持按名称自动匹配、手动选择以及上传小图标，并内置 Netflix、ChatGPT、账单、购物、旅行、工作等常用类型。
+- 上传图标会在浏览器本地缩放为 64×64 PNG，服务端校验 PNG 文件头并限制在 32 KB；不联网查询品牌，不保留上传原图。
+- 文件夹图标已在侧栏、桌面端与移动端移动菜单中统一显示，数据库升级会自动为旧文件夹补充默认图标。
+- 补充收信规则、自定义文件夹、图标自动匹配、手动图标保留和上传格式安全边界的回归测试。

+- 修复手机端删除自定义文件夹时菜单先消失、确认框无法显示的问题，文件夹菜单现在与移动侧栏保持在同一交互层中。
+- 删除文件夹前会稳定显示确认信息，提交后显示处理中状态，避免重复操作；文件夹内邮件仍会安全移回收件箱。
+- 修复手机侧栏中新建文件夹弹窗被侧栏遮挡或立即关闭的问题，侧栏退出后再打开创建界面。
+- 重做手机端“新建规则 / 编辑规则”布局：标题、表单与底部操作区改为纵向结构，内容区域可独立滚动。
+- 优化规则条件与动作的窄屏排列，字段和运算符并排、输入框独占一行，添加与删除按钮保持易点击且不会挤出屏幕。
+- 规则底部创建和取消按钮固定可见并适配手机安全区域，多条件、多动作时仍可顺畅滚动和提交。
+- 优化通用确认弹窗的手机宽度和按钮触控尺寸，减少误触并避免贴边显示。

 | 现象 | Gmail 显示 SPF 和 DMARC 通过，但 NewSzxcn 发出的邮件 DKIM 验证失败；同内容的 NodeSeek 对照邮件三项认证均通过。 |
 | 诊断 | NewSzxcn 邮件的 relaxed 正文哈希与 Gmail 收到的 `bh` 精确一致，排除正文传输修改；邮件签名无法由当前 DNS 公钥验证，说明发信时使用了不同私钥。`key not secure` 仅表示 DNSSEC 未验证，TXT 分段也属于正常 DNS 表示。 |
 | 根因 | DKIM 同步任务会覆盖容器内密钥文件，但 Rspamd 已载入的签名密钥不会随文件替换自动更新，域名重建或密钥变化后可能继续使用内存中的旧私钥。 |
 | 实现 | DKIM 同步改为先比较密钥内容；相同密钥不再重复替换，密钥新增或变化后立即重新载入 Rspamd；后台 DNS 检查从“仅判断 DKIM 记录存在”升级为核对实际 `p=` 公钥，明确区分缺失与公钥不一致；新增密钥同步和 DNS 公钥匹配回归，并纳入 CI 与发布检查。 |
 | 兼容性 | 不轮换现有 DKIM 密钥、不修改 DNS；已有数据库、邮件和域名配置保持不变。 |
