[Exim] X-RBL-Warning:

The Exim3 spec says that rbl/warn results in X-RBL-Warning: headers being added to
the message. The Exim4 spec is silent on this issue. Can you confirm that Exim4
also produces the same headers?

A subsidiary question, for Exim4, is: If a "warn dnslist ..." statement in an ACL
adds an X-RBL-Warning: header, can routers doing a verify for a subsequent verify
statement in the same ACL see that header? If not, at what stage can Exim check for
them?

What I am planning is for users to opt in to spam rejection on a individual basis,
so I want a router to check for the presence of the header and the user's name in
the opt-in list.

Phil.
