As it shows that this is not possible, you might change your mind to
implement it in your exim configuration as it is not too hard. For me, the
following router seems to work:
tagging:
driver = redirect
require_files = /server/exim/tagging/$local_part
condition = ${if match{$header_subject:}{(?im)${rxquote:${readfile{/server/exim/tagging/$local_part}{}}}}{no}{yes}}
headers_add = "Subject: ${readfile{/server/exim/tagging/$local_part}{}}$rheader_subject:"
headers_remove = subject
data = $local_part@$domain
The redirection to the same address does not cause a loop as exim is smart
enough to recognize it. Anyhow in my configuration I use
redirect_router = ... to the following router to increase performance.
Create /server/exim/tagging/mh+bugtraq with the content "[bugtraq]" should
start the tagging. Probably it is necessary to adapt the path to your
installation assuming it is not in /server/exim/...
Improvement suggestions are welcome.
