Looking at the docs, it expects a colon separated list of domains
only, but it is also expanded.

"The global option dkim_verify_signers can be set to a colon-separated
list of DKIM domains or identities for which the ACL acl_smtp_dkim is
called. It is expanded when the message has been received."

The expansion gives you what you were looking for. The
dkim_verify_signers setting itself doesn't know to convert a raw file
name to a readfile like the lists do. It could either be added to the
code or it can be better documented that it doesn't work like regular
lists in that regard. I do not know how much work it would be, I have
not looked at the code, won't have time until maybe next week.
