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

BOUNCE(8) System Manager's Manual BOUNCE(8)
NAME
bounce - Postfix message bounce or defer daemon
SYNOPSIS
bounce [generic Postfix daemon options]
DESCRIPTION
The bounce daemon maintains per-message log files with non-delivery status information. Each log file is named after the queue file that it
corresponds to, and is kept in a queue subdirectory named after the service name in the master.cf file (either bounce or defer). This pro-
gram expects to be run from the master(8) process manager.
The bounce daemon processes two types of service requests:
o Append a recipient status record to a per-message log file.
o Post a bounce message, with a copy of a log file and of the corresponding message. When the bounce is posted successfully, the log
file is deleted.
The software does a best effort to notify the sender that there was a problem. A notification is sent even when the log file or original
message cannot be read.
Optionally, a client can request that the per-message log file be deleted when the requested operation fails. This is used by clients that
cannot retry transactions by themselves, and that depend on retry logic in their own client.
STANDARDS
RFC 822 (ARPA Internet Text Messages)
RFC 1894 (Delivery Status Notifications)
DIAGNOSTICS
Problems and transactions are logged to syslogd(8).
BUGS
The log files use an ad-hoc, unstructured format. This will have to change in order to easily support standard delivery status notifica-
tions.
CONFIGURATION PARAMETERS
The following main.cf parameters are especially relevant to this program. See the Postfix main.cf file for syntax details and for default
values. Use the postfix reload command after a configuration change.
bounce_notice_recipient
The recipient of single bounce postmaster notices.
2bounce_notice_recipient
The recipient of double bounce postmaster notices.
delay_notice_recipient
The recipient of "delayed mail" postmaster notices.
bounce_size_limit
Limit the amount of original message context that is sent in a non-delivery notification.
mail_name
Use this mail system name in the introductory text at the start of a bounce message.
notify_classes
Notify the postmaster of bounced mail when this parameter includes the bounce class. For privacy reasons, the message body is not
included.
