It's this simple:

Instead of putting a call to procmail in your .forward, first, set up 
/etc/postfix/main.cf with the following line:

mailbox_command = /usr/bin/procmail

and reload postfix. Now, postfix will default to using procmail as its 
local delivery agent.

Now, set up /etc/procmailrc like so:

USER=`whoami`

:0 fw
| spamc

:0 e
{
         EXITCODE=$?
}

Now, set up the amanda user's .procmailrc rules like so:

:0:
* ^From.*no-re...@sns.amazonaws.com
|$HOME/retrieveArchive.tcl

:0:
*
! hel...@deepsoft.com

Voila!
