SMTPMail-drogon

Simple Mail for the Drogon framework.

It is made as a plugin for the drogon framework. It can be included into the drogon build with little modification of the class declaration.

Updates

• [ 09-05-2023 ] Fixed TLS update by HadesD.
• [ 13-06-2022 ] Fixed vulnerability issues reported by Sam.
• [ 13-09-2021 ] Added HTML content support.
• [ 23-12-2020 ] Added DNS support.

Acknowledgement

• The implementation takes SMTPClient for Qt from kelvins as reference.
• There requires a delay SSL encryption from the Tcp-socket (named TcpClient in trantor/drogon) and the major author of drogon reponsed quickly.

Download to the plugin directory of the target drogon app, E.g. ~/drogon-app/plugins

$ git clone https://github.com/ihmc3jn09hk/SMTPMail-drogon.git
