It uses awk with the field-separator of |.

It checks if the second field ($2) matches two different regexes, /regex1/ or /regex2/, and if it does, sets field 2 blank ($2="")

Then it replaces || with | in the entire line, to delete field 2 completely.

You'd implement it in your case by putting the regexes you wanted in /regex1/ and /regex2/.

bouncesaying

bouncesaying(1)                                               General Commands Manual                                              bouncesaying(1)

NAME

       bouncesaying - perhaps bounce each incoming message

SYNOPSIS

       in .qmail: |bouncesaying error [ program [ arg ...  ] ]

DESCRIPTION

       bouncesaying  feeds  each  new mail message to program with the given arguments.  If program exits 0, bouncesaying prints error and bounces
       the message.

       If program exits 111, bouncesaying exits 111, so delivery will be retried later.

       If program exits anything else (or does not exist), bouncesaying exits 0, so the rest of .qmail will be processed as usual.

       Note that it is not safe for program to fork a child that reads the message in the background.

       If program is not supplied, bouncesaying always bounces the message:

          |bouncesaying 'This address no longer accepts mail.'

       WARNING: If you create a .qmail file to enable bouncesaying, make sure to also add a line specifying delivery to your normal mailbox.
