⁠Postfix and Dovecot Email Server

This Docker image sets up a simple email server with Postfix and Dovecot. It allows you to easily deploy an email server for your domain. Imap is not configured. Just pop3 and smtp.

⁠Configuration Parameters

⁠SERVER_HOSTNAME

• Set the hostname of your mail server. For example, if your domain is "example.com", set SERVER_HOSTNAME to "example.com". Email addresses will be in the format [email protected].

⁠AUTH

• Use this parameter to create email users. The format is <user>:<password>. To add multiple users, separate each user/password pair with a semicolon ;. For example, <user1>:<password1>;<user2>:<password2>.

⁠SMTP_PORT

• Smtp port. Default: 25.

⁠POP3_PORT

• Pop3 port. Default: 110.

⁠How to Use

⁠1. Run the Docker Container

docker run -d -p 25:25 -p 110:110 -e SERVER_HOSTNAME=example.com -e AUTH="user1:password1;user2:password2" email-server

Replace "example.com" with your domain name and "user1:password1;user2:password2" with your desired email users and passwords.

⁠3. Start Sending and Receiving Emails

Your email server is now running and ready to send and receive emails.

⁠Additional Notes

• Make sure to set up DNS records (MX, SPF, DKIM, etc.) for your domain to ensure proper email delivery.
• For security reasons, consider using SSL/TLS certificates for encrypted communication with your email server.
