reverse proxy for smtp servers
to handle client requests, improving security, performance, and scalability.

clients send their requests to the reverse proxy,
which routes them to the appropriate servers
acting as a single, secure access point.
Key Benefits:
- Security
It can block malicious requests, encrypt traffic,
and protect backend servers from direct attacks. - Performance

of a single server and ensuring greater availability. - Scalability
It allows you to add or remove backend servers without service interruption,
offering the ability to handle growing traffic.
