I've found a way to send the message to an email address. It's a bit of a
hack, but..  Basically you output your log to a file, and have a cron job
that watches for that file, emails its contents, and deletes it.  I'm using
it to email a pager.

1- Configure your source line properly for the type of log you are catching
2 - Add a destination file rule
3 - Add a filter to filter for what you're looking for
4 - Add a log with above source, filter, and destination
5 - Install this script in /usr/bin or wherever
6 - Add a cron job such as the example that follows

Sample syslog-ng.conf
------------------------------------------
options { sync (0);
          time_reopen (10);
          log_fifo_size (1000);
          long_hostnames (off);
          use_dns (yes);
          use_fqdn (no);
          create_dirs (no);
          keep_hostname (yes);
        };

source s_sys             { unix-stream ("/dev/log"); internal(); };
source s_remote          { udp(ip(0.0.0.0) port(514)); };

destination d_powerpay   { file("/var/log/powerpay"); };
destination d_powerpay_email  { file("/var/log/powerpay_email"); };

filter f_emerg                { level(emerg); };
filter f_powerpay             { facility(local1); };

log { source(s_remote); filter(f_powerpay); destination(d_powerpay); };
log { source(s_remote); filter(f_powerpay); filter(f_emerg);
destination(d_powerpay_email); };
log { source(s_remote); filter(DEFAULT); destination(d_mesg); };
-------------------------------------

Sample cron entry
------------------------------------
5,10,15,20,25,30,35,40,45,50,55,0 * * * * /usr/bin/mail_log.sh
/var/log/powerpay_email inet_admin@ceridian.ca
-----------------------------------

mail_log.sh script
-----------------------------------
#!/bin/bash
#
# mail_log.sh
# by John Delisle john_delisle@ceridian.ca
# Feb 28 2001
#
#
# If a file $1 exists, it mails its contents to $2, and deletes $1
#
#

MAILPROG="/usr/sbin/mail"

if [ $# != 2 ]; then
        echo "Usage: $0 file_to_check email_address"
        exit 1;
fi

if [ ! -e $1 ]; then
        #echo "$1 not found, exiting"
        exit 2;
else
        $MAILPROG $2 < $1
        echo "Message Sent to $2";
        echo "Removing $2";
        rm $2
fi

exit 0;

Maciek, have you had any success sending email using this method?  I'm
trying to get syslog-ng to send an email when a certain alert comes in.

                    Please respond to

                    syslog-ng

Hello,

I have following configuration on my machine:

           source logdev { unix-stream("/dev/log"); };
           destination foo { program("/home/foo/.bin/loglogs.pl"); };
           filter f_foo { not priority(debug) and not facility(mail); };
           log { source(logdev); filter(f_foo); destination(foo); };

File /home/foo/.bin/loglogs.pl come as follows:

           #!/usr/bin/perl
           open FOO, ">/tmp/loglog.log";
           while ( <STDIN> ) {
                     print FOO $_;
           }
           close FOO;

Could anybody tell why file /tmp/loglog.log stays empty no matter what I
do?

Greets,
                     --Maciek
