I'm trying to insert "X-Sources" headers into my mailheaders for
debugging purposes. Unforunately documentation about this is very
rare yet on the net.
- use exim-4.34+ or greater
- install exim with embedded perl;
Debian/Ubuntu users: "apt-get install exim-daemon-heavy"
- insert into main/00_local_macros a line like:
perl_startup = do '/etc/exim4/mailheaderadd.pl'
Setup a perl script at /etc/exim4/mailheaderadd.pl, which contains:
sub mailheaderadd {
my $xsource = $ENV{'X-SOURCE'};
my $xsourceargs = $ENV{'X-SOURCE-ARGS'};
my $xsourcedir = $ENV{'X-SOURCE-DIR'};
my $headers = "X-Source: ${xsource}\n"
. "X-Source-Args: ${xsourceargs}\n"
. "X-Source-Dir: ${xsourcedir}";
return ($headers);
}
Then use the appropriate transport and insert the add_headers line:
procmail_pipe:
[...]
headers_add = "${perl{mailheaderadd}}"
That's all I merged from different sources.
As a result, my script doesn't work. All three environment variables
seem to be empty:
Date: Wed, 02 Mar 2011 23:52:27 +0100
X-Source:
X-Source-Args:
X-Source-Dir:
What's wrong?
