killing virus e-mails with file types
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
As Martin Pitt mentioned here, you can filter on the file types of
attachments to e-mails to eliminate the "Microsoft Upgrade" e-mail
attachments.
I do it in an even simpler way (keep in mind I don't really have bandwidth
limitations). I have my mail filter (kmail) set up so it trashes any mail
message with the string ".exe", ".pif", ".bat", or ".scr".
I also eliminate messages containing ".com", but in those messages, I require
that they _don't_ contain "http" to prevent killing messages because of a
link.
I guess I could see why someone who developed in windows might be getting
.bat or .scr files (I assume .scr is an extension for windows scripts?).
However, I can't think of any legitimate reason for someone to send me an
executable file. Any legit executable is going to be bigger than most people
are going to want to receive via e-mail anyway. That's what the web is for.
