By "Stacking", I mean the common pattern where Foo: the-ur-foo
is rewritten into X-Original-Foo: the-ur-foo Foo: the-no-longer-ur-foo I am not thinking of a header with addresses here, so Exim's rewrite mechanism doesn't apply. Is there a "best" or "accepted" way to do this? In particular, can I do this in an ACL: add_header = X-Original-Foo: $h_foo: set acl_m_original_foo = $h_foo: remove_header = Foo add_header = Foo: the-no-longer-$acl_m_original_foo (I am not sure if the last add_header trum^H^H^H^Hoverrides the preceding remove_header.) And if not in ACL, can I do something similar in a router or transport? -- Ian -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
