[own domain email] SPF records point to domain or subdomain?

Thanks a lot for the post on how to set up an own email with domain. It's working well so far. I just had one question. Do the SPF record need to point to domain.tlp or to the subdomain created by mailbox.org where I put the security key? It seems to me it has to point to domain.tlp, but then it would prevent me from pointing the domain also to my own website/IP? Thanks a lot for the help!

You configure a DNS TXT record with the value "v=spf1 include:mailbox.org" for the main domain. If you also want to use your own website/IP you would use "v=spf1 a include:mailbox.org". If you don't care if others are able to forward the emails you are sending them, you could use "v=spf1 a include:mailbox.org -all". Please see http://www.openspf.org/SPF_Record_Syntax for more details.

Thanks for your reply. I have configured the record with "v=spf1 a include:mailbox.org -all". Strangely, sending email from the address works, but sending to the email gives this error:

An error occurred while sending mail. The mail server responded:

5.1.2 <email@domain.com>: Recipient address rejected: Domain not found.

Please check the message recipient "email@domain.com" and try again.

You have no A and MX records. In this case you can leave "v=spf1 include:mailbox.org -all", but remember it will break forwarding. Configure the domain in your mailbox.org account, add the user, then configure the required MX records from https://support-en.mailbox.org/knowledge-base/article/e-mail-addresses-of-your-own-domain

The auto-configuration DNS records (not really needed) should be configured for the main domain, not the subdomain.
