Drops all attachments on messages 
that have a MIME type, determined

drop-attachments-by-mim

etype (<MIME type>[,  

<optional comment>]) 

Drops all attachments on messages 
that have a given MIME type. This 
action does not attempt to ascertain 
the MIME type by file extension and 
so it also does not examine the 
contents of archives.
