Ok, I now have a router configured to do this. Can anyone see any
glaring problems with this?

condition = ${if and {{match {$header_subject:} {^magic.*}} {eq {$sender_address}{eric@???}}} {true} {false} }
headers_remove ="from:"
headers_add = "From: paul@???"


This, conbined with a rewrite rule to turn fred@ukc into eric@ukc seems
to do the trick (There is no problem having the From: header as the last
header is there?).

Not neat but it will get us out of the hole for now (unless anyone spots
a glaring problem!)
