Deleting a message from the Postfix queue

The postsuper command has an option to delete Postfix message queue files. To delete the message with queue id ABCDEF, perhaps obtained from mailq output, one would use:

# postsuper -d ABCDEF

To delete a large number of files one would use:

# postsuper -d - < filename-with-queue-ids

To delete all messages in queue:

#postsuper -d ALL

How to Delete Messages from Queues in Exchange Server 2003



1. Click Start, point to All Programs, point to Microsoft Exchange, and then click System Manager.


2. Double-click Servers, double-click the server that you want, and then click Queues.


3. Right-click the queue that you want to modify, and then click Freeze to freeze the queue.


4. Click Find Messages, and then click Find Now to find messages in the queue.


5. Right-click the message that you want to delete, and then click one of the following options:
• Click Delete (no NDR) to delete messages from the queue without sending a non-delivery report (NDR) to the senders.
• Click Delete (with NDR) to delete messages from the queue and send an NDR to the senders of the messages.

Access lists on the PIX firewall can only be applied to traffic entering an interface, not traffic that is exiting an interface. This is unlike Cisco router, on which access lists can be applied in either direction.

The syntac for access lists on the PIX firewall is ver similar to that of Cisco routers. The key difference is that access lists on the PIX firewalls use standard wildcard masks, whereas on routers they use inverse wildcard masks. For example, when blcoking a 24-bit subnet, you would use a mask of 255.255.255.0 on a PIX firewall and a mask of 0.0.0.0.255 on Cisco router.

To let traffic flow from a high security level to a lower level, use the nat and global commands. For the opposite direction, from lower to higher, use the static and access-list commands.

The design of an access list should start with a definition of what is going to be allowed and then proceed to what is going to be denied.

A good practice is to add an explicit deny all statement to the end of an access list so you remember it is there when yu do a show access-list command. You can see how many packets

Inbound traffic is lower security-level to higher security-level

Outbound traffic is higher security-level to lower security-level

On some RedHat AS 3.0 installations, laus/audit.d logs 20M a day and never logrotates. You can just do the following:

/etc/init.d/audit stop
rpm -f /dev/auditrpm --erase laus
/etc/init.d/crond restart
/etc/init.d/atd restart
rm -rf /var/log/audit.d

I've got some bounced mail in the queue which is not being accepted by the remote site. How can I remove it from the queue?
