Edit the source code, receive.c, around line 1775, to set some variable
based upon this.

Beware that this:
----------------------------8< cut here >8------------------------------
<"some:other"@???>
----------------------------8< cut here >8------------------------------
would be a valid header line, with a header name of '<"some'.

The valid characters for a header-name are the printable US-ASCII
characters. This is dictated by RFC 5322. That line could as well be:
----------------------------8< cut here >8------------------------------
<someother@???>:
----------------------------8< cut here >8------------------------------
and '<someother@???>' would be the header name. If Exim didn't
accept it, then Exim would be buggy.

I think you may want to consider using separate spam-filtering software
to accomplish your goals.
