Qmail-scanner

Adding disclaimers to mail

You can do it, it involves creating a text, or html file with the disclaimer text, and a regular expression for the domains to apply it to. Note: Altering email bodies like this is considered not very nice, and can break some peoples clients. You have been warned1

1) make sure altermime is installed

yum install altermime

2) Run qmail-scanner-reconfigure, this detects altermime and enables it

qmail-scanner-reconfigure

3) Create disclaimer files in /var/spool/qscan

 text_disclaimer.txt
 html_disclaimer.html

3) Edit /var/qmail/bin/qmail-scanner-queue.pl change the following entries for your regex, and disclaimer text and/or html files

my $altermime_text='text_disclaimer.txt';
my $altermime_html='html_disclaimer.html';
my $disclaimer_regex = 'exampledomain.com';
