Internal Server Error. Try again later - Trying to add a domain in Mail module

Hi there. I just installed WORKSPACE community and trying to add a domain fails every time.

I also modified my DNS accordingly with the registrar, waited, made sure the changes propagated to no avail.

docker ps:

Any suggestions please?

Hello @smaru
Have you added DKIM record to your DNS settings first? Setting up mail server.
if so, you can check whether there’re any DNS issues with this tool: https://mxtoolbox.com/
If the issue still persists, please provide us with entire Community server and Mail server logs folders. For the docker installation, they’re located here (on the host, if you used official installation guide):
/app/onlyoffice/CommunityServer/logs/
/app/onlyoffice/MailServer/logs/
