Redmine发送测试邮件遇Net::ReadTimeout错误,请求协助解决
Redmine配置Office365 SMTP发送邮件超时问题排查
环境配置详情
Environment: Redmine version 5.1.1.stable Ruby version 3.0.2-p107 (2021-07-07) [x86_64-linux-gnu] Rails version 6.1.7.6 Environment production Database adapter Mysql2 Mailer queue ActiveJob::QueueAdapters::AsyncAdapter Mailer delivery smtp Redmine settings: Redmine theme Default SCM: Git 2.34.1 Filesystem Redmine plugins: no plugin installed
当前SMTP配置文件
配置文件路径:/home/ubuntu/redmine-5.1.1/config/configuration.yml
# specific configuration options for development environment # that overrides the default ones production: email_delivery: delivery_method: :smtp smtp_settings: #ssl: true #tls: true enable_starttls_auto: true #openssl_verify_mode: 'none' address: "smtp.office365.com" port: 587 #domain: "" # Replace with your domain authentication: :login user_name: "google.com" # Replace with your Office 365 email address password: "*******" # Replace with your Office 365 email password
报错信息
An error occurred while sending mail (Net::ReadTimeout with #<Socket:(closed)>)
已验证项
- 可通过telnet连通smtp.office365.com 587端口
- 安全组已开放587端口至任意地址
需调整的SMTP配置操作
- 修正邮箱账号:当前
user_name填写的google.com无效,必须替换为真实的Office365邮箱地址(如xxx@yourdomain.onmicrosoft.com或自定义域名绑定的邮箱) - 启用domain配置:取消
domain行的注释,填写你的Office365租户域名(如yourdomain.onmicrosoft.com或公司自定义域名) - 明确TLS设置:取消
tls: true的注释,保持ssl: true注释状态(587端口使用TLS协议) - 添加超时参数:在
smtp_settings中增加超时配置,避免读取超时:open_timeout: 30 read_timeout: 30 - 确认密码有效性:如果邮箱开启了多因素认证(MFA),需使用应用专用密码而非普通登录密码;未开启MFA则确保密码填写正确
- 临时验证证书(可选):若服务器无法信任Office365的SSL证书,可临时取消
openssl_verify_mode: 'none'的注释(仅测试用,生产环境建议配置系统证书信任)
调整后的参考配置:
production: email_delivery: delivery_method: :smtp smtp_settings: #ssl: true tls: true enable_starttls_auto: true #openssl_verify_mode: 'none' address: "smtp.office365.com" port: 587 domain: "yourdomain.onmicrosoft.com" # 替换为你的租户域名 authentication: :login user_name: "your-email@yourdomain.onmicrosoft.com" # 替换为真实邮箱 password: "your-app-password-or-regular-password" # 替换为对应密码 open_timeout: 30 read_timeout: 30
