There is a growing need for HCL Domino to support sending SMTP emails through a SOCKS proxy. This enhancement would greatly benefit users operating in environments with stringent network security requirements.
Current Situation
Currently, HCL Domino does not provide native support for sending SMTP emails through a SOCKS proxy. Other mail transfer agents (MTAs) like Postfix and Exim, although they do not have native support, can utilize external tools such as tsocks or proxychains to achieve this functionality. These tools route SMTP traffic through a SOCKS proxy, offering essential security and flexibility in enterprise and cloud environments.
Benefits of SOCKS Proxy Support
Enhanced Security: Integration with existing network security policies allows better control over outbound traffic.
Cloud Compatibility: Facilitates secure email transmission in environments like AWS where direct internet access is often restricted.
Simplified Administration: Reduces reliance on external tools, lowering administrative overhead and minimizing potential points of failure.
Proposed Enhancement
It is proposed to add an option in the Domino SMTP settings to specify a SOCKS proxy server, including support for SOCKS5 authentication. This would enable Domino to route SMTP traffic through the SOCKS proxy natively.
