I host a number of maillists using exim and mysql. Some of the lists
need the To: and From: headers altered in the generated messages. In my
router for the lists my headers_remove option works fine using an
lsearch on a file with entries for each list's $local_part, as in
headers_remove = ${lookup{$local_part}lsearch{/etc/exim/mlremhdr}}
where the file mlremhdr contains entries like
mylist: To:From
I also want to add headers in the same manner using another file which
also contains an entry for each list with the headers_add content, as in
headers_add = ${lookup{$local_part}lsearch{/etc/exim/mladdhdr}}
where the file mladdhdr contains entries like
mylist: To: [email protected] \n\ From: [email protected]
I cannot get the content presented by the lsearch to show up in a format
acceptable to the router's headers_add option. I have tried many
variations in formatting the To: and From: header content, including
separate lines for each header. A single header works fine, as in
mylist: To: [email protected]
but specifying multiple headers will not generate the desired format of
headers_add To: [email protected] \n\
From: [email protected]
which works if manually coded in the router.
Can anyone tell me how to make this work? My maillist router looks like
this:
maillist:
driver = redirect
syntax_errors_to = [email protected]
local_parts = /etc/exim/maillists
data = ${lookup{$local_part}lsearch{/etc/exim/maillists} \
{${lookup mysql{select email from $value}}}}
headers_remove = ${lookup{$local_part}lsearch{/etc/exim/mlremhdr}}
headers_add = ${lookup{$local_part}lsearch{/etc/exim/mladdhdr}}
