## Source File
|
||
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/08_Networking/ctp-topic-36-sendgrid-as-an-email-service.md]]
|
||
|
||
## Summary
|
||
|
||
- 核心主题：SendGrid 被采用为云转换计划的标准化邮件服务
|
||
- 问题域：替换不安全的语义网关和受限制的 SES 方案
|
||
- 方法/机制：直接发送（需 TLS）或通过中继服务器发送架构
|
||
- 结论价值：SendGrid 提供 1000 收件人/邮件限制、实时监控、双因素认证、端到端加密
|
||
|
||
## Key Claims
|
||
|
||
- SendGrid 已被采用为经典和新 landing zones 的标准邮件服务
|
||
- 当前语义网关存在安全问题：通过 port 25 中继到公网，且托管在即将停用的本地网络
|
||
- 当前 SES 限制为每邮件仅 50 个收件人
|
||
- SendGrid 支持每邮件最多 1000 个收件人
|
||
- 支持计划涵盖每月 500 万封邮件
|
||
- 日志保留 7 天，API 密钥每 180 天轮换
|
||
|
||
## Key Concepts
|
||
|
||
- [[SendGrid]]：Twilio 旗下的企业级邮件服务，被 CTP 采用为标准
|
||
- [[Cyber-Suite]]：PSAC 更新发布的网络安全标准文档
|
||
