how to find "setup.sh" from mailserver-docker to setup DKIM

[theoneandonly-vector]

I want to setup dkim, but I have no clue how to achieve it as I can't find "setup.sh" from: https://github.com/tomav/docker-mailserver/

Hi @theoneandonly-vector,

the script is in the root dir of that repository (here https://github.com/tomav/docker-mailserver/blob/master/setup.sh). I cannot say though, if it will work out of the box when running the script inside of this project.

this command doesn't run into an error, also the other commands seem to work fine for me (debug show logs / login etc..) but where are the DKIM-keys be saved (Can't find them in the directory as the original project states) -> this is not an issue on the original project, because when I run it there, it works as expected.

I don't have any experience with the setup script of docker-mailserver. Please post the full command you are executing and the response from the script. Since its a bash script it could be helpful to call it with bash -x.

The description at https://github.com/tomav/docker-mailserver#generate-dkim-keys speaks of the result being stored in config/opendkim/keys/domain.tld/mail.txt. In their example compose this is the bind mount location for /tmp/docker-mailserver (see https://github.com/tomav/docker-mailserver/blob/master/docker-compose.yml.dist#L17). So I would guess you can find the information when you exec into the mail container and look in /tmp/docker-mailserver/opendkim/keys/domain.tld/mail.txt.

there's no "key"-folder there.

let's close this one:

1. login to the mail-docker
2. run: generate-dkim-config generate-dkim-domain neutronix.ch
3. exit docker (mail) pasting the content of config/opendkim/keys/domain.tld/mail.txt in your mail.tld.hosts zone.
