Bug#609764: Please add a macro do disable DKIM

[Yuri D'Elia]

Package: exim4-config
Version: 4.72-3
Severity: wishlist

DKIM is enabled by default lately (though it only generates a warning),
but there seems no easy way to disable it.

Searching through exim archives it seems that you need the following:

require control = dkim_disable_verify

early in the rcpt ACL (probably just before/after SPF).
Could you please add a conditional like DISABLE_CHECK_DKIM to turn off this
feature?

Thanks
