Yes. However you can make the router much more readable as follows:
mail2news:
local_parts = lsearch;/etc/exim4/mail2news
driver = redirect
data = "|/usr/lib/news/bin/mailpost -a [EMAIL PROTECTED] \
${extract {1}{,} {$local_part_data} }"
pipe_transport = address_pipe
errors_to = postmaster
headers_add = Subject: ${sg {$rh_subject:} \
{\\\[${extract {2}{,} ($local_part_data} }\\\] }{} }
headers_remove =
newsgroups:distribution:x-spam-report:received:errors-to:subject
Always check that the condition you are writing isn't supported directly
by a standard condition: you will avoid a lot of ugly string expansions.
Note that headers_add doesn't need a trailing \n or quotes.
I think it would be better to do the Subject: mangling in the mailpost
program - perhaps make the subject tag a command-line argument?
