New version of bogofilter-milter.pl

[Tom Anderson]

I've made some changes to bogofilter-milter.pl to remedy a few problems 
I was having, one being that it wasn't writing to my syslog... I fixed 
that one.  Another being that the rejection message wasn't working and 
still isn't.  Instead of the given setreply, it returns "554 5.7.1 
Command rejected".  I still can't figure that one out after reading the 
Sendmail::Milter docs several times.  Anyway here's my patch thus far:

70a71,73
 > # The syslog facility to which to log messages -- see syslog(3) docs
 > my $facility = 'LOG_MAIL';
 >
142a146,153
 > # Rejection options
 > my $rcode = "550"; # three-digit RFC 821 SMTP reply
 > my $xcode = "5.7.1"; # extended RFC 2034 reply code
 > my $message = "This message has been classified as spam.\n" .
 >             "If it is not spam, please try rewording your message " .
 >             "and sending it again.  Otherwise, please contact " .
 >             "recipient via phone, snail mail, IM, or another means.";

< openlog($whoami, 'pid', 'mail');

 > openlog($whoami, 'pid', $facility);

<           $ctx->setreply(550, "5.7.1", "Your message looks like spam.\n" .
<                          "If it isn't, resend it with $magic_string " .
<                          "in the Subject line.");
---
 >           $ctx->setreply($rcode, $xcode, $message);

Also, in case anyone is interested, I created a Gentoo start/stop script:

#!/sbin/runscript

depend() {
         need net
         use logger
}

start() {
         ebegin "Starting bogofilter-milter"

         if [ -f /var/run/bogofilter-milter.pid ]; then
                 rm -f /var/run/bogofilter-milter.pid
         fi

         if [ -S /var/run/bogofilter-milter.sock ]; then
                 rm -f /var/run/bogofilter-milter.sock
         fi

         start-stop-daemon --start --quiet --pidfile 
/var/run/bogofilter-milter.pid --exec /usr/sbin/bogofilter-milter.pl -- 
--daemon
         eend $? "Failed to start bogofilter-milter"
}

stop() {
         ebegin "Stopping bogofilter-milter"
         start-stop-daemon --stop --quiet --pidfile 
/var/run/bogofilter-milter.pid
         eend $? "Failed to stop bogofilter-milter"
}
