What version of Exim?
To clarify: is it ok when the transport_filter is used, but there was no
attachment?
It's always possible we have a bug there... on a quick look I don't see
a testcase in the regression testsuite covering
dkim-with-transport_filter. There's certainly special coding in
the source for the case; running under debug you should see
"dkim signing via file" and _not_ see
"dkim signing direct-mode"
