cufilter - Filter emails through Mail::CheckUser SYNOPSIS
Add the following lines to your ~/.procmailrc: # Filter mail through Mail::CheckUser :0f | /usr/bin/cufilter DESCRIPTION
When email messages are filtered through this program using the procmail settings as outlined in the SYNOPSYS, the email address in the "From:" header is passed through Mail::CheckUser to ensure validity. If there is a problem with the email address, the "Subject:" header is modified to show which email address failed along with the failure reason. No messages are lost, but it provides an easy way for the mail client to organize, sort, or filter based on the subject tweaks. EXAMPLES
Lets say a spammer sends a message with the following headers: From: god@heaven.org To: you@host.com Subject: Happy Pill Then the new headers might change to the following: From: god@heaven.org To: you@host.com Subject: [CU!god@heaven.org!DNS failure: SERVFAIL] Happy Pill This makes it easy to filter for mail clients. INSTALL
This file can be installed into /usr/bin/cufilter and is intended to be utilized through the procmail functionality by adding the following lines to your ~/.procmailrc configuration. # Filter mail through Mail::CheckUser :0f | /usr/bin/cufilter AUTHORS
