Configure AntiSpam Blocker SMTP Routes with Priority of Destination host
In the cisco antispam blocker, it has a setting to configure multiple destination host IP address for SMTP route. It is located at Network --> SMTP Routes --> Select "domain name" --> destination hosts. We can add mutiple IP address for hosts there.
If we have entered 3 x IP address, we found that it will randomly try SMTP Route host for mail delivery. Will it possible to configure the multiple host delivery with priority (Like the MX record preference setting concept in DNS) ? I.e. It will always try hosts 1 first unless it is not available.
Re: Configure AntiSpam Blocker SMTP Routes with Priority of Dest
If you set up multiple SMTP routes, the system will cycle through them in a round robin fashion based on number of SMTP connections. However, if you specify multiple hosts in one SMTP route, the blocker will try them in the order you type them. See below:
Per this example, the blocker will deliver to 192.168.1.25 first, and fail over to 192.168.1.26 if for some reason .25 does not respond.
However, if it is done like this:
The blocker will alternate between the destinations. Hope this helps!
