marcoacierno/docker-postfix repository overview

⁠docker-postfix

run postfix with smtp authentication (sasldb) in a docker container. TLS and OpenDKIM support are optional.

⁠Requirement

  • Docker 1.0

⁠Installation

  1. Build image

    $ sudo docker pull catatnight/postfix

⁠Usage

  1. Create postfix container with smtp authentication

    $ sudo docker run -p 25:25 \
		-e maildomain=mail.example.com -e smtp_user=user:pwd \
		--name postfix -d catatnight/postfix
# Set multiple user credentials: -e smtp_user=user1:pwd1,user2:pwd2,...,userN:pwdN

  2. Enable OpenDKIM: save your domain key .private in /path/to/domainkeys

    $ sudo docker run -p 25:25 \
		-e maildomain=mail.example.com -e smtp_user=user:pwd \
		-v /path/to/domainkeys:/etc/opendkim/domainkeys \
		--name postfix -d catatnight/postfix

  3. Enable TLS(587): save your SSL certificates .key and .crt to /path/to/certs

    $ sudo docker run -p 587:587 \
		-e maildomain=mail.example.com -e smtp_user=user:pwd \
		-v /path/to/certs:/etc/postfix/certs \
		--name postfix -d catatnight/postfix

⁠Note

  • Login credential should be set to ([email protected], password) in Smtp Client
  • You can assign the port of MTA on the host machine to one other than 25 (postfix how-to⁠)
  • Read the reference below to find out how to generate domain keys and add public key to the domain's DNS records
