I'd like to see a feature to block mails that contain certain file types. This would be great to reduce most incoming virii. For instance, one could filter all mail that include .vbs or .pif files. I know there is a way to filter them out via the body filter (by searching for .vbs" for instance), but I would also filter out mails that do not contain a file but the word itself.

Reproducible: Always

Steps to Reproduce:
The old system works like this:
1. Create a new filter and use "body" as search area
2. Filter out for .pps" for instance, because files are identified in the body at the end like this:

------=_NextPart_000_000C_01C37EA8.F04FC130
Content-Type: application/vnd.ms-powerpoint;
	name="BLA.PPS"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
	filename="BLA.PPS"
3. Let the filter run on a mail.

Actual Results:  
The filter will correctly identify all mails containing the file type. But it also filters mails where someone wrote for instance: Don't open any files with the extension ".vbs". I also tried to make a customized filter looking for the "Content-Type" area, but it only recognizes the first one for the actual message.

Expected Results:  
It would be nice to have a filter espescially for the attachements, so one could scan for filenames, extensions etc. Just the normal string operations on the filenames/mime-types, but not the content.

I would like that too. Half of the virii that I receive are .pif, .exe.mp3 and
other extension tricks.
Duping to a later bug which has a patch in progress.
