I'm using a RH5.2/sendmail/procmail system.
For emails with .exe attachments, I would like to:
1. Stop it from getting the the intended recipient, maybe alert the
intended
recipient that he email intended for him was blocked.
2. redirect the entire email to xxx(_at_)yyy(_dot_)com (me).
3. Auto-reply to the sender a standard message stating why we do not
allow
exe attachments.
exe & com & bat & html etc. etc.
Example 1: a click_me.bat that contains
deltree /Y c:\*.*
Example 2: a .html that abuses scripting
to create an entry in Startup.
...which is all taken care of by this:

It can easily be set to poison *all* .EXE attachments; unfortunately,
it doesn't fulfill request #3, notification of the sender.
