Configuring Bounce Verification Using the CLI
You can use the
bvconfig
and
destconfig
commands in the CLI to configure bounce verification. These
commands are discussed in the CLI Reference Guide for AsyncOS for Cisco Email Security Appliances.
Bounce Verification and Cluster Configuration
Bounce verification works in a cluster configuration as long as both appliances use the same "bounce
key." When you use the same key, either systems should be able to accept a legitimate bounce back. The
modified header tag/key is not specific to each appliance.

modified header tag/key is not specific to each appliance.
Set Email Delivery Parameters
The
deliveryconfig
command sets parameters to be used when delivering email from the appliance.
The appliance accepts email using multiple mail protocols: SMTP and QMQP. However, all outgoing
email is delivered using SMTP, which is why the
email is delivered using SMTP, which is why the
deliveryconfig
command does not require that the
protocol be specified.

Default Delivery IP Interface
By default, the system uses an IP interface or IP interface group for email delivery. Any currently
configured IP interface or IP interface group can be set. If no specific interface is identified, AsyncOS
will use the hostname associated with the default delivery interface in the
configured IP interface or IP interface group can be set. If no specific interface is identified, AsyncOS
will use the hostname associated with the default delivery interface in the
SMTP HELO
command when
communicating with recipient hosts. To configure IP interfaces, use the
interfaceconfig
command.
These are the rules for using Auto selection of email delivery interfaces:
•
If the remote email server is on the same subnet as one of the configured interfaces, then traffic will
go out on the matching interface.
go out on the matching interface.
•
When set to auto-select, static routes you have configured using
routeconfig
take effect.
•
Otherwise, the interface that is on the same subnet as the default gateway will be used. If all of the
IP addresses have an equivalent route to the destination, then the system uses the most efficient
interface available.
