Our solution here is to have amanda send the email to itself (via the mailto option in our amanda.conf file). The amanda account has a procmail filter that saves a copy to a local file and forwards another copy on to the required persons.
$ cat /services/amanda/.procmailrc
# Set up environment
PATH=/bin:/usr/bin
MAILDIR=$HOME
LOGFILE=$MAILDIR/.procmail/procmail.log
# Forward a copy of amanda's mail to [EMAIL PROTECTED] and save a copy of it
locally
