Altermime is a small utility that allows you to append a disclaimer to all outbound emails on a cPanel server.
1. Installing altermime
You should be able to copy and paste the following commands in. You’ll need to be root.
cd /usr/local/src/ wget pldaniels.com/altermime/altermime-0.3.10.tar.gz tar xvfz altermime-0.3.10.tar.gz cd altermime-0.3.10 make make install
2. Setup Disclaimer Text
Create two disclaimer files. One is text and the other is for HTML.
Text file
nano /usr/local/etc/exim/textdisclaimer
Add your disclaimer text.
------------- incredigeek.com
HTML File
Create the HTML disclaimer file with
nano /usr/local/etc/exim/htmldisclaimer
And add your disclaimer HTML to the file. Example:
<p> ----- <br /> <a href="http://www.incredigeek.com">incredigeek.com </a> </p>
3. Modify Exim Configuration
Now that we have the disclaimer files set up, we can move on to configuring Exim so the disclaimer text gets added to every email sent out.
Open up WHM and go to Exim Configuration Editor -> Advanced Editor
A. Configuring Routers Configuration
Find the ROUTERS CONFIGURATION section. We will add some configuration in the “Section: PREROUTERS”
Add disclaimer to Single Domain
Paste in the following to add the disclaimer to a single domain. Replace “incredigeek.com” with your domain.
disclaimer:
driver = dnslookup
domains = ! +local_domains
transport = ${if eq {$sender_address_domain}{incredigeek.com}{disclaimer_smtp}{remote_smtp}}
no_more
Add Disclaimer to Entire Server (Optional)
If you would rather apply the disclaimer to the entire server, use the following.
disclaimer: driver = dnslookup domains = ! +local_domains transport = disclaimer_smtp
B. Configure Transports Configuration
Once we have that added we can find the “TRANSPORTS CONFIGURATION” section and under the first “Section: TRANSPORTSTART” add
disclaimer_smtp: driver = smtp transport_filter = /usr/local/bin/altermime --input=- --disclaimer=/usr/local/etc/exim/textdisclaimer --disclaimer-html=/usr/local/etc/exim/htmldisclaimer size_addition = 1
That should be everything that you need. Send a test email to an external email account to verify that it works.
Note that it looks like sending an email locally to email addresses on the same domain or to yourself bypass the filter and do not get the disclaimer added.
