Due to a required change in our network configuration, incoming emails will be delayed for up to 72 hours. Your outgoing email will not be affected.
You will receive all the delayed incoming emails once the configuration updates are complete. If you are expecting critical email that cannot wait, you should contact the sender and make other arrangements (courier, fax, etc.) to receive the information.
The only reason we changed though was to prevent these problems in the future. We've got a 2 server system and ended up taking one of the servers out of the config. I created 2 new "floating" ip addresses that I can add to any server as a secondary ip. This allows the services to be very mobile. My only problem is the MX record was in place back in March and was simply incorrect and filling the wrong mail queue. I've got it straightened out now, and it looks like most domains that matter are already updated after 2 hours.Originally posted by: Saltin
This is one of the reasons to use a mail proxy.
I can't think of any instances where I would have to change an MX record.
Just plug in the new server at the same address.....
