Example
In this example, the 
filter
 command is used to create three new filters:
The first filter is named 
big_messages
. It uses the 
body-size
 rule to drop messages larger than 10 
megabytes. 
The second filter is named 
no_mp3s
. It uses the 
attachment-filename
 rule to drop messages that 
contain attachments with the filename extension of 
.mp3
The third filter is named 
mailfrompm
. It uses 
mail-from
 rule examines all mail from 
postmaster@example.com
 and blind-carbon copies 
administrator@example.com
Using the 
filter -> list
 subcommand, the filters are listed to confirm that they are active and valid, 
and then the first and last filters are switched in position using the 
move
 subcommand. Finally, the 
changes are committed so that the filters take effect.
