NimbostratusRedirect mail traffic
We are moving Data centers. There will be a period of time where we may want to redirect mail traffic. We can used DNS but that takes time to propagate. I have used multiple irules for URL and http t...
I would configure this with MX records.
MX 10 mail.olddomain.com
MX 20 mail.newdomain.com
Disable the virtual server for mail.newdomain.com until the migration.
Mailservers will first try MX 10 to send the email. If it is not responding they will send it to the next MX record in the list.
When you start the migration enable the virtual server for mail.newdomain.com and disable the virtual server for mail.olddomain.com
Sending mailservers will automatically start sending mail to mail.newdomain.com.
Cheers,
