sendmail to exchange w/ldap problem slightly OT SOLVED

Tue Nov 4 18:29:37 GMT 2008

I gave up on 4.7; found a way to install 4.3 on another box and shovel
that drive into the R200.  Now it works.

Goofy computers.

I've seen that but haven't played with it.  The implementation I've used
quite a number of times, but seemingly doesn't want to play ball on
centos 4.7 (probably a perl thing, but I'm a perl-idiot), works well for
us.  I like it because it doesn't talk to the exchange box very often so
if for whatever reason it can't nothing bounces except addresses that
may have changed  on the exchange side since that last time they talked.

It appears that it's complaining about the declaration and/or use of the
variables, but I didn't write the code in the first place and couldn't
perl myself out of a paper bag so I'm a little stuck as to why it's
kosher on 4.3 but fails on 4.7.

what ware you trying to achieve here? If you want to know if the end
email address exists before accepting the email in the incoming sendmail
then sendmail Sender Address Verification
(http://smfs.sourceforge.net/smf-sav.html) will do this for you..

	I've been using a hunk of code to have MS/Sendmail query
exchange 2000/2003 boxes for some time with no problems.  Today, I'm
setting up a nice little dell R200 and so I had to use Centos4.7 over my
default 4.3 to get sata support.  

	Any help, much appreciated...

	When I run the code, I get this silliness:

	[root at spamfilter mail]# ./sendmail-ldap.sh

	Name "main::EMAILS" used only once: possible typo at
./sendmail-ldap.sh line 57, <DATA> line 275.

	Name "main::DOMAINS" used only once: possible typo at
./sendmail-ldap.sh line 60, <DATA> line 275.

	starting ./sendmail-ldap.sh at Tue Nov  4 08:55:00 EST 2008

	Undefined subroutine &main::extract_emails called at
./sendmail-ldap.sh line 51, <DATA> line 466.

	[root at spamfilter mail]#

	Code here:

	#!/usr/bin/perl -w

	use strict;

	use Net::LDAP;

	print "starting $0 at ", `date`;

	my $debug = 0;

	my %mails = ();

	my $hostname = `hostname -f`;

	chomp $hostname;

	my %domains = ($hostname => 1);

	my $dir = "/etc/mail";

	my $emails_file = "$dir/temp-emails";

	my $domains_file = "$dir/temp-domains";

	my $access_file = "$dir/access";

	my @prefixes = ("postmaster", "abuse", "root");

	my @servers =

	(     "mail.boogidy.com"

	);

	sub extract_emails($);

	my $ldap = undef;

	my $mesg = undef;

	for my $server (@servers)

	{       print STDERR "Connecting to server $server...\n" if
$debug;

	        $ldap = Net::LDAP->new( $server ) and last;

	}

	$ldap or die "Unable to connect to any LDAP servers.";

	print STDERR "Binding...\n" if $debug;

	$mesg = $ldap->bind(

	        dn => 'BOOGIDY\Administrator',

	        password => 'redacted'

	) or die "Could not bind LDAP: $@";

	$mesg->code and die $mesg->error;

	print STDERR "Searching...\n" if $debug;

	$mesg = $ldap->search(

	        base   => "dc=boogidy,dc=local",

	        filter =>
"(|(objectClass=publicFolder)(&(sAMAccountName=*)(mail=*)))"

	);

	print STDERR "Checking code...\n" if $debug;

	$mesg->code and die $mesg->error;

	extract_emails($mesg);

	print STDERR "Unbinding...\n" if $debug;

	$mesg = $ldap->unbind;   # take down session

	open EMAILS, "> $emails_file"

	        or die("Could not open > $emails_file\n$!");

	open DOMAINS, "> $domains_file"

	        or die("Could not open > $domains_file\n$!");

	open ACCESS, "> $access_file"

	        or die("Could not open > $access_file\n$!");

	print ACCESS << "END";
