File name. Drops all attachments on messages that have a 
filename that match the given regular expression. Archive 
file attachments (zip, tar) will be dropped if they contain a 
file that matches.

File size. Drops all attachments on the message that, in raw 
encoded form, are equal to or greater than the size (in bytes) 
given. Note that for archive or compressed files, this action 
does not examine the uncompressed size, but rather the size 
of the actual attachment itself.

File type. Drops all attachments on messages that match the 
given “fingerprint” of the file. Archive file attachments (zip, 
tar) will be dropped if they contain a file that matches.

MIME type. Drops all attachments on messages that have 
a given MIME type. 

Image Analysis Verdict. Drops attachments for image 
attachments that match the image verdict specified. Valid 
image analysis verdicts include: Suspect, Inappropriate, 
Suspect or Inappropriate, Unscannable, or Clean. 

Replacement message. The optional comment serves as the 
means to modify the text used to replace the attachment that 
was dropped. Attachment footers simply append to the 
message.
