Prevention of infinite mail loop with Auto Responder

This mostly happens when the mail account using autoreponder gets lot of spam mail, and as many of these spam mails use bogus From addresses, this account also recieves many mailer-daemon responses while replying to these bogus email addresses.

1) Edit /home/virtual/FILESYSTEMTEMPLATE/sendmail/etc/smrsh/responder.sh (This file is hardlinked into all the domains having autoresponder enabled as
/home/virtual/[domainname]/etc/smrsh/responder.sh)

and comment out:

so it looks like:

Then insert after it:

2) Create the file called auto.rc with the following lines:

Copy this file to /home/virtual/[domainname]/etc/ for all the domains using autoresponder.
(You may want to use virtDomain.sh to automatically copy or create this file when ever a new domain is added)

Now anything coming from MAILER-DAEMON or postmaster that goes to the responder will be sent to /dev/null.

Anything else will be sent to the responder.

Channel Bonding Interfaces

Linux allows administrators to bind multiple network interfaces together into a single channel using the bonding kernel module and a special network interface called a channel bonding interface. Channel bonding enables two or more network interfaces to act as one, simultaneously increasing the bandwidth and providing redundancy.

To create a channel bonding interface, create a file in the /etc/sysconfig/network-scripts/ directory called ifcfg-bond[N], replacing [N] with the number for the interface, such as 0.

The contents of the file can be identical to whatever type of interface that is getting bonded, such as an Ethernet interface. The only difference is that the DEVICE= directive must be bond[N], replacing [N] with the number for the interface.

The following is a sample channel bonding configuration file:

For example, if channel bonding two Ethernet interfaces, both eth0 and eth1 may look like the following example:

In this example, replace [N] with the numerical value for the interface.
