PostFix configuration

Hello

I'm new in this forum so I don't know if this is the correct page for my question.
We have a server ,running RedHat 3, with installed Postfix 2.2.11 with Amavis , SpamAssassin and ClamAv.
This server is used by several years without problem.

Now we have some some problems with spam/bounced messages and we have the necessity, if possible , to send forwarding errors ( in case of errors during forward of messages to some mailling list we have configured ) only to a local mail system administrator on our system , so that this person can verify/fix the problem.

I have seen that in the master.cf file there is a line in which we can decide what to do with bounce messages ( default operation is "bounce" ).
We have set it to "discard" but i don't think this is the correct solution - in this case simply postfix deletes the bounce message.

Also, when relaying authenticated mail, we need to add the authenticated user as a
header in the relayed mail.

Please, can you help me with this problems / configurations?

Thank you

Mail::SpamAssassin::Plugin::Pyzor(3)			User Contributed Perl Documentation		      Mail::SpamAssassin::Plugin::Pyzor(3)

NAME
Mail::SpamAssassin::Plugin::Pyzor - perform Pyzor check of messages SYNOPSIS
loadplugin Mail::SpamAssassin::Plugin::Pyzor DESCRIPTION
Pyzor is a collaborative, networked system to detect and block spam using identifying digests of messages. See http://pyzor.sourceforge.net/ for more information about Pyzor. USER OPTIONS
use_pyzor (0|1) (default: 1) Whether to use Pyzor, if it is available. pyzor_max NUMBER (default: 5) This option sets how often a message's body checksum must have been reported to the Pyzor server before SpamAssassin will consider the Pyzor check as matched. As most clients should not be auto-reporting these checksums, you should set this to a relatively low value, e.g. 5. ADMINISTRATOR OPTIONS
pyzor_timeout n (default: 3.5) How many seconds you wait for Pyzor to complete, before scanning continues without the Pyzor results. You can configure Pyzor to have its own per-server timeout. Set this plugin's timeout with that in mind. This plugin's timeout is a maximum ceiling. If Pyzor takes longer than this to complete its communication with all servers, no results are used by SpamAssassin. Pyzor servers do not yet synchronize their servers, so it can be beneficial to check and report to more than one. See the pyzor-users mailing list for alternate servers that are not published via 'pyzor discover'. If you are using multiple Pyzor servers, a good rule of thumb would be to set the SpamAssassin plugin's timeout to be the same or just a bit more than the per-server Pyzor timeout (e.g., 3.5 and 2 for two Pyzor servers). If more than one of your Pyzor servers is always timing out, consider removing one of them. pyzor_options options Specify additional options to the pyzor(1) command. Please note that only characters in the range [0-9A-Za-z ,._/-] are allowed for security reasons. pyzor_path STRING This option tells SpamAssassin specifically where to find the "pyzor" client instead of relying on SpamAssassin to find it in the current PATH. Note that if taint mode is enabled in the Perl interpreter, you should use this, as the current PATH will have been cleared. perl v5.12.1 2010-03-16 Mail::SpamAssassin::Plugin::Pyzor(3)
