DKIM about docker-mailserver

[aaronchn]

Hi @jeboehm,

In my opinion, as one of the core functions of the mail server, the strategy about do the dkim and spf or dmarc ... should achieve the most basic functions in the clearest steps based on the minimum components.

If we need a better experience or more dream story in future, we can call that basic function with a higher level tool at a higher level of perspective.

Let me say it directly that Is it possible to consider to create DKIM keypairs or spf? with simple command line interface?

Please forgive my English level, thank you for your code.

FYI: docker-mailserver/docker-mailserver#975 (comment) .

Hey @aaronchn
DKIM support is now added to the current master branch. It is completely configurable via the management interface. Feel free to try it out!
I appreciate your feedback. :)

Hi @jeboehm

To genarate the default DKIM setting for the current domain is a better idea?
With your solution user have to enable Web service If they want to use DKIM feature, this is not they wanted sometimes.

Here is my scrawl that I want to try it in entrypoint.sh or new dkimkeygen.sh with Filter service, but encounter permitted error.

if ! [ -f /media/dkim/dkim_selectors.map ]
then
chown -R rspamd /media/dkim
chmod 777 /media/dkim
touch /media/dkim/dkim_selectors.map
echo "${DOMAIN} ${CURDATE}" > /media/dkim/dkim_selectors.map
rspamadm dkim_keygen -d ${DOMAIN} -s ${CURDATE} -k /media/dkim/${DOMAIN}.${CURDATE}.key > /media/dkim/${DOMAIN}.${CURDATE}.pub
echo "DKIM public key has been generated:"
cat /media/dkim/${DOMAIN}.${CURDATE}.pub
fi

Honestly, I don't have much skill in this area. If my suggestion is valuable, please consider updating your code. If my suggestion is not feasible, if you are willing , Can you try to guide me how to solve this problem?

Thanks!
