⁠postfix-relayhost

Run postfix with smtp relay.

⁠Requirement

  • Docker 1.0

⁠Installation

  1. Build image
$ docker pull nanasess/postfix-relayhost

⁠Usage

  1. Create postfix container with relayhost

    Save your relay_password to /path/to/relay_password

    [relayhost.example.com]:587	[email protected]:password

    Execute the docker run command.

    $ docker run -p 1025:25 \
	-e mynetworks="172.17.0.0/24 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128"
	-e maildomain=mail.example.com \
	-e relayhost="[relayhost.example.com]:587" \
	-v "/path/to/relay_password:/etc/postfix/relay_password" \
	--name postfix-relayhost -d nanasess/postfix-relayhost

  2. 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

  3. 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

  4. 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
