.TH mailer "8" "October 2013" "Lars Vogdt" "John" .SH NAME Mailer \- notify users about crackable passwords .SH SYNOPSIS .B mailer .br .SH DESCRIPTION .B mailer is a script to send mail to all users whose passwords got cracked. This is not always a good idea, though, since lots of people do not check their e-mail or ignore such messages, and the messages can be a hint for crackers. You should probably deploy proactive password strength checking, such as with passwdqc, before you ask users to change their passwords - whether using this script or otherwise. And you should edit the message inside the script before possibly using it.
