Postfix-Relay
Postfix-Relay
Docker-Anwendung from ZappyZap's Repository
Übersicht
This runs Postfix (as a relay) in Docker.
Most home ISPs block port 25, so outbound emails must be relayed through an external SMTP server (e.g., Gmail).
This container acts as a single collections point for devices needing to send email.
⚠️ Postfix acts as an open relay. As such, this is not meant to be run on the internet, only on a trusted internal network! ⚠️
Requirements
You must already have a account on an external SMTP server (e.g., Gmail, AWS SES, etc...).
Your external SMTP server must be using encryption (i.e., plaintext is not allowed)
