View source for HowTos/EmailDisclaimer

One question that gets asked every-so-often is how to add a disclaimer to all outbound email. There are a lot of names for this thing, some may call it a global footer, some may say common signature, some might call it one of those legal thingies at the bottom of the email. Whatever you call it, if you want one, here:s how to get it.

== Method ==

Scalix uses sendmail as its outgoing MTA. So the place you'll want to configure this is going to be right there at the bottom of the stack in sendmail. There is a milter architecture in sendmail, which is short for mail filter. If you want to know more about the milter architecture, check out [http://www.sendmail.org/doc/sendmail-current/libmilter/docs/ Filtering Mail with Sendmail] for a full description of how it works.

There is a plug-in for this architecture called milter-disclaimer which does exactly what we'll need.

== Software ==

The first thing you'll want to do is ensure that your version of sendmail includes support for milters. The first version of sendmail with milter support enabled by default was sendmail 8.12.0 released on September 8, 2001.

True to the flexible spirit of open source software, there are a couple different bits of code you could use to add the actual disclaimer, including [http://aeschi.ch.eu.org/milter/ cvgfilter.c] and [http://www.mimedefang.com/ MIMEDefang] among others. The one I'd recommend using is [http://www.ledge.co.za/software/disclaimermilter/ DisclaimerMilter] available from [http://www.ledge.co.za/software/disclaimermilter/ http://www.ledge.co.za/software/disclaimermilter/].
