But according to spec.txt ISTM it should work as is:
$header_<header name>: or $h_<header name>:
...
If the message does not contain the given header, the
expansion item is replaced by an empty string.

Or just
condition = ${if def:h_X-Mail-from:}
Either should work. I think the issue is more likely to be one of
the other questions I asked earlier.
