•
The first filter is named

. 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.
