In today’s digital age, email remains a cornerstone of communication for individuals and businesses. While traditional email hosting services offer convenience, self-hosting your email server provides unparalleled control, privacy, and customization. By taking charge of your email infrastructure, you can tailor it to your needs, ensuring optimal performance and security.
What Are Self-Hosted Email Servers?
A self-hosted email server is a server you own and manage dedicated to handling your email services. Unlike traditional email hosting, where you rent space on a shared server, self-hosting gives you complete control over your email environment. You can install and configure your preferred email server software, manage user accounts, and implement security measures.
