Host status is down - How to change MX records?

allylaurente · ‎09-20-2012

Hi,

Im having an issue of relaying emails from Iron Port to our smtp server. One of the node in our NLB SMTP server is down and for some reason the host was removed from the NLB. The issue is I cannot telnet to the current MX records that is showing in the "hoststatus".

How should I change the Ordered IP Address and MX records? I need to update them with the correct one.

(Machine mx1.admin.domain.edu)> hoststatus

Recipient host:
[]> domain.edu

Host mail status for: 'domain.edu'

I would try entering an SMTP Route. Enter the old hostname for the domain and then add the new machine as the destination.

You could also use the (undocumented) command delivernow but that will deliver ALL mail and if it runs into any issues like rate limits it will cause mail to bounce.
