What is a Debian 11 Email Server?
A Debian 11 email server is a software application that runs on a Linux server and enables businesses to send and receive email messages. It’s a comprehensive email solution that can be used to manage email accounts, domains, and user access. It provides features such as spam filtering, virus scanning, and email forwarding.
How Does a Debian 11 Email Server Work?
When you send an email message, it is first sent to your Debian 11 email server. The server then verifies the sender’s identity and checks the message for spam and viruses. If the message passes these checks, it is forwarded to the recipient’s email server, where it is stored until the recipient downloads it. When the recipient downloads the message, a copy is also stored on their email server.
A Debian 11 email server can be used with various email clients, such as Microsoft Outlook, Mozilla Thunderbird, or any other client that supports the IMAP or POP3 protocols. Once you have set up your email accounts on the server, you can configure your email client to connect to your server and start sending and receiving messages.
