My company is moving offices this weekend. We have one email server at the old office. I'd like to move it this Friday night. It would be cool if we didn't lose any email.
Our DNS holds an MX record for our domain with a TTL of 1800 seconds (30 mins) and an MX level of 10 Choice 1: 1-change the MX record to point to the new IP address which the mail server will have in the new building 2-unplug the mail server and drive it to the new building (10 mins away), assign the box the new ip address Is anyone likely to ignore the 1800 TTL and continue sending email to the old ip address for longer than 30 mins? during the downtime, will sending email attempts fail or simply keep trying? Choice 2: 1-set up a new mail server in the new building 2- add an MX record with an MX record of 20 3- set up a store and forward config to forward the email to the original email server the idea being that someone sending email will first try the email with the 10 MX level, and failing that will try the 20 MX level server. that server will accept the email and attempt to forward it to the original email server. it should keep trying for the 10 minutes the original email server is down and then succeed once it's back up at the new place. who likes choice 1? choice 2? other, more intelligent, choices?
