Messages are not signed with DKIM

Wanwalker a posé une question...
When sending mail from custom domain alias' I am notified that my messages are not signed by DKIM. I can also confirm this using mail-tester.com.

I have no problems sending mail from @riseup.net alias'. This problem ONLY happens when sending it from alias' with custom domains. And yes, I have added and verified the custom domain alias at account.riseup.net/aliases.

Here is an example of what I receive when trying to send emails. (Emails do actually send, but I see this warning):

----------

This is the mail system at host mx1.riseup.net.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

: host mail.minifree.org[178.21.20.23] said: 550
authentication required (in reply to RCPT TO command)

----------

Is this an issue on Riseup's end? Thanks in advance for the help.

Hi,

We cannot dkim sign domains we don't own, in the future we will be able to do this but not right now. But this error is not related to that problem, I will dig this problem and ask minifree.org people about it

Thanks you for the reply. I did some more research into what DKIM does, so that makes more sense to me.

Thank you for looking into the auth error for me. I have been working on my DNS configuration, and now have a score of 9/10 on mail-tester.com (DKIM being the only negative point). This is for the custom alias I am sending email from. So I'm not sure why I still get that 550 response. Thanks again!

Hi,

I'm sorry but still having heard something from minifree.org. Their mailserver was not allowing to deliver e-mail, it seems that they fixed it but i was waiting for a reply here :/
