Docker-Mailserver mailserver/docker-mailserver:latest https://hub.docker.com/r/mailserver/docker-mailserver bridge bash false https://forums.unraid.net/topic/122875-support-docker-mailserver/ https://github.com/docker-mailserver/docker-mailserver A production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Antispam, Antivirus, etc.). Only configuration files, no SQL database. Keep it simple and versioned. Easy to deploy and upgrade. <h3> Preperations </h3> This short guide will help you to set up a mailserver. To keep the mailserver running, there are some important points to consider, like at least one configured mail account, SSL type, hostname, etc. If these points are missing, they will be mentioned in the Docker logs to simplify troubleshooting. Make sure, you got an domain and a static IP adress to setup your mailserver. MX and A DNS entries are needed. After that, portforward the mentioned ports in your router. <h3> Initial steps: </h3> The following placeholders will be used: user is the mail account you create. example.com is the domain you are using. mail.example.com is the FQDN of the mailserver. password is the password for your mail account. 1. At first, setup the environment variables and change --hostname mail.example.com in the Extra Parameters (advanced view) as needed. Choose custom Network Type and set an fixed IP Adress. (didn't tested other options) 2. Create an e-mail account by starting the container with Post arguments (advanced view): setup email add user@example.com 'password' setup email add admin@company.org 'Ch33rs#M8!' (for example) 3. Remove the post arguments. 4. Start container and check the logs. Optional and recommended: Open Container Console and type in... setup config dkim 5. Try to connect to the server with an e-mail client. 6. Test sending and recieving mails Optional: If everything works, you can enable Fail2Ban in the environment variables For further informations, visit the extended documention: https://docker-mailserver.github.io/docker-mailserver/edge/ Network:Other https://avatars.githubusercontent.com/u/76868633?s=200&v=4 --hostname mail.example.com --restart always --cap-add=NET_ADMIN --cap-add=SYS_PTRACE 1651251277 A production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Antispam, Antivirus, etc.).
