IIRC the redirect router returns DECLINED when data is empty. So it does
not use the values of header_remove/header_add.

To quote the relevant from from spec.txt:

From 22.10:
<quote>
data
Type: string, expanded
Default: unset

This option is mutually exclusive with file. One or other of them must
be set, but not both. The contents of data are expanded, and then used
as the list of forwarding items, or as a set of filtering instructions.
If the expansion is forced to fail, or the result is an empty string or
a string that has no effect (consists entirely of comments), the router
declines.
</quote>

From 15:
<quote>
headers_add
Type: string, expanded
Default: unset

This option specifies a string of text that is expanded at routing time,
and associated with any addresses that are processed by the router when
delivering a message. This option has no effect when an address is just
being verified.
</quote>

... as the router declines, the address is NOT processed.
