ssl container startup fails, dkim dmarc

[kzpm]

Your docker-mailserver runs nice on my machine.

I have a few questions:

1. When I issue docker start or docker restart jeboehm/mailserver-ssl:latest container the startup exits almost immediately.
   docker logs 7ecb6ed322h shows the following info:
   `
   Generating a 2048 bit RSA private key
   No SSL certificate found. Creating a new one...
   ........+++
   ...............................................+++

My question:
How to enable the ssl-container?

Mailing to domains outside the domain I created the mailserver for, fails.
I suppose that it has to do with opendkim, dmarc and spf.
How can I setup dkim, dmarc and spf in my isp-dns zone?

Hi kzpm,

the SSL container is designed to run only once when no official certificate exists. So everything is fine here.

In general there should be no problems when you don't have DMARC & stuff set up. The logs of the mta container would help here.
Currently, neither DMARC or OpenDKIM are supported by docker-mailserver.

As far as I understand, rspamd can already sign e-mails with DKIM.

https://rspamd.com/doc/modules/dkim_signing.html

https://workaround.org/ispmail/stretch/prevent-spoofing-dkim/

So, is that possible with docker-mailserver? And if so, how and where do I configure it?

Hi @tlappe ,
currently this is not possible, because the image does not support it.
