Delete Postfix Queue based on domain name or email pattern

I found this particluar perl file very effective. This scripts give me the option to delete mail from the queue based on domain name or email id pattern. I have found this script in www.cyberciti.biz

#!/usr/bin/perl

$REGEXP = shift || die "no email-adress given (regexp-style, e.g. bl.*\@yahoo.com)!";

@data = qx</usr/sbin/postqueue -p>;
for (@data) {
  if (/^(\w+)(\*|\!)?\s/) {
     $queue_id = $1;
  }
  if($queue_id) {
    if (/$REGEXP/i) {
      $Q{$queue_id} = 1;
      $queue_id = "";
    }
  }
}

#open(POSTSUPER,"|cat") || die "couldn't open postsuper" ;
open(POSTSUPER,"|postsuper -d -") || die "couldn't open postsuper" ;

foreach (keys %Q) {
  print POSTSUPER "$_\n";
};
close(POSTSUPER);

Save this scripts and change the chmod to 755 (make the scripts executable). Now you can run the following command

./script.pl domain.com which will delete the domain.com mail from the mailq.
./script.pl xyz which will delete all queued messages that contain the word "xyz" in the e-mail address.

This is good to know where the MySQL data are stored. People usually backup there MySQL database when the server is up using mysqldump syntex. But what happen when server crash or server is show kernel panic? It’s easy. Boot the Server using any live distro (Knoppix, Ubuntu or Linux/CentOS in rescue mode). Mount your HDD. MySQL data’s are stored in /var/lib/mysql. So after mouting your HDD the location will be /your_mount_point/var/lib/mysql. Copy the files in your new server. Check the ownership. It should be mysql:mysql. Start the mysqld service. You are done.
