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
```bash
$ sudo docker pull catatnight/postfix
```
## Usage
1. Create postfix container with smtp authentication
```bash
$ 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```
```bash
$ 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```
```bash
$ 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](http://www.postfix.org/MULTI_INSTANCE_README.html))
+ Read the reference below to find out how to generate domain keys and add public key to the domain's DNS records
