New script for handling of MIME-encoded e-mail

[Yngve Svendsen]

I have made a new, and substantially more powerful version of the script 
that filters MIME-encoded e-mail before it is piped into GNATS. As well as 
fully decoding headers and bodies of messages, it now handles multi-part 
messages containing attachments.

It strips out the parts of a message that are not plain text, decoding 
those parts and saving them to an archive directory. Separate directories 
are created on-the-fly to hold the contents of each message. A reference is 
then inserted into the original message, stating the location of the saved 
file. The parts of the message that were originally in plaintext get their 
quoted printables translated and are otherwise left alone.

Details, together with the script itself, is available from 
http://sources.redhat.com/gnats/mimedecode.html

We have been running this script in production for a week, and it has 
behaved perfectly well. However, do read the warnings at the end of the 
page mentioned.
