ISPConfig3.2-Debian12-Nginx-DKIM emails are not being signed with DKIM keys

It has nothing to do with DKIM. It was pointed out by till because 465 SSL is kinda obsolete and you should use 587 with Starttls.

Is the rspamd service running at all? Does it restart just fine? Check the Journal of the service, any errors?

 

I am sorry I misunderstood that port 587 authentication would be required, my mistake!
Rspamd service is running and now also the log is being populated BTW.

 

So now DKIM should work. If thats not the case check the following things:

• Is DKIM activate for the mail domain in question in ISPConfig?
• Is the correct DNS record for DKIM set in the zone of the mail domain in question (If the domain uses external DNS server you need to add the record there)
• Does the rspamd.log log any lines reagarding DKIM when sending a testmail?

 

OK, here is what has happened. I had run previously, as recommended by till, "ispconfig_update.sh --force". Unfortunately didn't solve the issue. But now, I have also done a resync of emails from within ISPconfig/tools. And to my great surprise, DKIM works correctly now. I am very happy, although I do not exactly understand how it had been fixed, lol. But I am not complaining. Thanks everybody for your kind advice, really appreciated.
