Description

opendkim-testkey -vv returns error invalid data set type.
By removing refile: from /etc/opendkim.conf the problem seems to be solved, as explained here https://serverfault.com/a/861701/377751.

Before:

$ opendkim-testkey -vv
opendkim-testkey: using default configfile /etc/opendkim.conf
opendkim-testkey: invalid data set type

After:

$ opendkim-testkey -vv
opendkim-testkey: using default configfile /etc/opendkim.conf
opendkim-testkey: record 0 for 'mail._domainkey.domain.tld' retrieved
opendkim-testkey: checking key 'mail._domainkey.domain.tld'
opendkim-testkey: key mail._domainkey.domain.tld not secure
opendkim-testkey: 1 keys checked; 1 pass, 0 fail
