Re: [exim-dev] Pass recipients to spamd

(this should have gone to exim-dev...)

Ok, since nobody objected (or nobody were interested), I made a small
patch (attached) it ran fine on my system the last days.

Even easier: There's already code for it in spool_mbox.c, but it put
only a single recipient into the header ($received_for). I changed this
to $recipients. The only problem is a probably very long line, but that
seems to be no problem for spamd (at least in my tests).

Even that is already there, so the changed Received: header was not
necessary (for spamd).
