Attachments are now stripped

[Roy Tennant]

In the wake of the Melissa virus recirculating, SunSITE system 
administrators implemented a script that automatically strips 
attachments from Web4Lib postings. The Web4Lib Posting Policy (see 
http://sunsite.berkeley.edu/Web4Lib/#Policy ) has long discouraged 
attachments; now they are simply forbidden.

The way this works is that a software filter examines each message 
for lines that start 'Content-type:'. If one of those lines does not 
also include 'text/plain', 'message', or 'multipart/digest', it 
erases that line and from that line to the end of the message.

When the filter erases an attachment, it inserts the following in the message:

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*         ---REMAINDER OF MESSAGE TRUNCATED---            *
*     This post contains a forbidden message format       *
*  (such as an attached file, a v-card, HTML formatting)  *
*    This mail list only accepts PLAIN TEXT               *
* If your postings display this message your mail program *
*   may not be set to send PLAIN TEXT ONLY and may need   *
*                      adjusting                          *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

To show you what this looks like, I am sending an attachment along 
with this message. Please let me know if you have any questions.
