Pkg exim4 users - Sep 2006 - Configuring daemon-heavy to use the acl_data_check hook

Greetings,

I understand from reading this site: http://duncanthrax.net/exiscan-acl/
and the Exim spec.txt file, that exiscan is now included with exim4.60.
I am eager to test the power of access control lists in exim. I have
configured exim4 according to the documentation, at least according to
the way I understand it. Is the following snippet correct? That is to say,
will exim4 recognize that I have some local acls defined in the file
/etc/exim4/local_acl and execute them?

  # This hook allows you to hook in your own ACLs without having to
  # modify this file. If you do it like we suggest, you''ll end up with
  # a small performance penalty since there is an additional file being
  # accessed. This doesn''t happen if you leave the macro unset.
  .ifdef CHECK_DATA_LOCAL_ACL_FILE
  .include CHECK_DATA_LOCAL_ACL_FILE = /etc/exim4/local_acl
  .endif


Thank you,

Jeremiah Foster

Ah, ok, Thanks Magnus. So to reiterate, leave the configuration file
un-edited and just add a file with my
macros under /etc/exim4 called exim4.conf.localmacros?

Thanks again,

Jeremiah

See http://pkg-exim4.alioth.debian.org/README/README.Debian.html,
chapter 2.1.3.

More confused than ever after reading both the above link and the
spec.txtfile. There is only
one mention of a .include Macro in both, this one:

"A macro at the start of a line may turn the line into a
comment line or a ".include" line."

But that does not tell me why I need the include line or the .includes
syntax.
Furthermore, from the web site:
http://pkg-exim4.alioth.debian.org/README/README.Debian.html
in section 2.1.2;
"The data files are documented in the exim4-config_files man page."

On my machine, I get;

 No manual entry for exim4-config_files

So I have no idea how to implement the sa-exiscan acl under debian. Is there
a specific document dealing with this
somewhere?

This is irrelevant for your case. I suspect that Philip meant to write
that

SOME_MACRO

at the beginning of a line might be a no-op if SOME_MACRO is defined
as "# something" or that it might cause a different file to be
included if SOME_MACRO is defined as ".include some-different-file".
Both cases are not relevant in a sane Debian setup.

Which include line do you mean you need?

http://wiki.debian.org/PkgExim4 says "The current README.Debian can be
found on the Web ([WWW] html [WWW] text). These two files are
generated each night from the XML Source in the [WWW] Subversion
Repository and might not be appropriate to any packaged version since
Development might be ahead of packaging."

This is a case where you have been "bitten": The README I was
referring you to is the README for the current development version,
and the man page you have been referred to is rather new.

Thanks for pointing this out. I have built a process that publishes
the current man pages for Debian exim on
http://pkg-exim4.alioth.debian.org/README/ . You can read up there.

sa-exiscan? You''re mixing up things.

What I know about exim''s spamassassin and antivirus integration, I
have learned from the exim documentation, and
from what''s now on http://www.exim.org/eximwiki/EximContentScanning

After using our packages for more than a year, I think you should have
learned how to move generic exim instructions to fit into Debian''s
configuration scheme. It''s not all _that_ different.

Marc
