包简介

Displays a lock next to the message if it was received using TLS. Requires TLS logging enabled in the MTA.

README 文档

README

Displays a small icon after the subject line that displays the (presumed) encryption state of received mails. This plugin parses the "Received" header for the last hop and checks if TLS was used. This requires TLS logging in the receiving MTA.

In Postfix this can be enabled by setting smtpd_tls_received_header = yes. Sendmail and Stalwart should work out of the box. Other MTAs have not been explicitly tested.

Note that while this talks about "encryption", this does not imply security. An encrypted mail may still be insecure, mostly because mailservers generally use "opportunistic TLS", where MITM attacks are possible. This also only validates the last hop of an email - some emails may run through multiple hops and we don't know anything about the security of these.

germancoding/tls_icon 适用场景与选型建议

germancoding/tls_icon 是一款基于 PHP 开发的 Composer 扩展包，目前已累计 7.06k 次下载、GitHub Stars 达 10，最近一次更新时间为 2021 年 07 月 09 日，在 PHP 生态内属于活跃度较高的组件。

它主要适用于以下技术方向：「logging」「ssl」「icon」「tls」等业务场景。在实际项目中，围绕这些方向常见需要落地的问题包括：接口对接、性能调优、并发安全、与既有框架（Laravel / ThinkPHP / Yii / Webman 等）的兼容适配，以及生产环境的日志埋点与稳定性保障。

我们在过去多个企业项目中使用过 germancoding/tls_icon 或与其功能相近的方案，如果你在选型或落地过程中遇到问题，例如 版本兼容、二次改造、私有化封装、与内部系统对接、生产 BUG 排查，欢迎联系我们协助评估。
