Context
I used the dkim configuration, but when I try to send an email, it gives a DKIM error
Site where I tested the mailheaders: https://mxtoolbox.com/Public/Tools/EmailHeaders.aspx
Expected Behavior
Properly signed DKIM signature
Actual Behavior
DKIM-Signature Not Correct
Possible Fix

Steps to Reproduce
Get latest image:
docker pull tvial/docker-mailserver:latest
Get the tools:
Download the docker-compose.yml, the .env and the setup.sh files:
curl -o setup.sh https://raw.githubusercontent.com/tomav/docker-mailserver/master/setup.sh; chmod a+x ./setup.sh
curl -o docker-compose.yml https://raw.githubusercontent.com/tomav/docker-mailserver/master/docker-compose.yml.dist
curl -o .env https://raw.githubusercontent.com/tomav/docker-mailserver/master/.env.dist
Create a docker-compose environment
Edit the .env to your liking. Adapt this file with your FQDN.

HOSTNAME=mail
DOMAINNAME=your-website.be
CONTAINER_NAME=mail
# empty => uses the `hostname` command to get the mail server's canonical hostname
# => Specify a fully-qualified domainname to serve mail for. This is used for many of the config features so if you can't set your hostname (e.g. you're in a container platform that doesn't let you) specify it in this environment variable.
OVERRIDE_HOSTNAME=your-website.be
Please note that:
- The
HOSTNAME shouldn't contain dot's, so dont take the domainname as HOSTNAME.
OVERRIDE_HOSTNAME should be the same as the hostname
Create your mail accounts
./setup.sh email add <email> [<password>]
# for example: ./setup.sh email add [email protected] password
Generate DKIM keys
./setup.sh config dkim
cat config/opendkim/keys/yourdomain.be/mail.txt
This will output something like this:
mail._domainkey IN TXT ( "v=DKIM1; h=sha256; k=rsa; "
"p=XXXXXXXXX"
"AAAAAA" ) ; ----- DKIM key mail for yourdomain.be
Put the following in in a TXT DNS record:
spin up the docker container:
docker-compose up -d mail
Now test if you can send an email with:
Install 'swaks': apt install swaks or brew install swaks.
Then:
sudo apt-get install libnet-ssleay-perl
sudo apt-get install libcrypt-ssleay-perl
swaks -f [email protected] --server 127.0.0.1:587 -tlsos --auth-user [email protected] -body "Dit bericht is van de server" -t <receiver-address>
My Environment
- Amount of RAM available: 2Gb
- Mailserver version used: latest version at 5 June 2019
- Docker version used: Docker version 18.09.3, build 774a1f4
- Environment settings relevant to the config: see steps to reproduce
- Any relevant stack traces ("Full trace" preferred): /
What already tried:
- Using 1024 bit dkim
- Updating to the latest mailserver version (5 June 2019)
