Maybe a Domain Factory customer is on the list and can open a support ticket.
The problem is that most so called DKIM verifiers on the web only glimpsed at
the RfC. When checking the DKIM record of DF with the help of online validators
that are returned on the first page of a search for "dkim check", I got the
following results:
- Mxtoolbox: All green, "DKIM public key present", "DKIM Syntax valid"
- DmarcAdvisor: All green, "Your DKIM record is valid", "The syntax of the
record is correct"
- Mimecast: Reports no errors
- Powerdmarc: "This record has been correctly setup", "No errors found"
- Dmarcian: "Congratulations! Your DKIM record is valid."
- Dmarcly: "Success! Everything appears fine with your DKIM record."
- Dnschecker: "This seems to be a valid DKIM Record."
The only validators which I found that correctly reported a problem are
Mailhardener ("The selector 'init_dkim' contains an underscore, some SMTP
implementations will not accept a DKIM selector with underscores. If possible,
choose a different selector without underscore") and Uriports ("The provided
DKIM selector is invalid").
