Zimbra Servers Coexistence

One of our members is planning to update a server in production with Zimbra 8.8.12 and 250 Mailboxes to another with version 8.8.15. The idea is to spin up a new server and install version 8.8.15, then migrate the mailboxes and, when the migration is complete, turn off the server with version 8.8.12. He asks if it's possible for the domain to handle two MX records? And is there a way to have them coexist? Ideally he'd like to configure the setup so that when someone sends an email to that domain it reaches the mailboxes (they are the same) of the two servers. The general feeling is that there's no easy way to accomplish a coexisting setup. Do you have a solution, or another way of handling the migration?

Who's sharing your IP?

Long-term WHTer MonteVesubio airs his suspicions that his hosting has some pretty disreputable websites hosted somewhere around his IP range - Not his actual IP, but close to it. He feels that this is a factor in Google rankings, what they call "to be in good neighborhoods", meaning that a host doesn't have a lot of spamming websites. He has no idea how to find out what kind of websites his hosting company has. He's seen mentioned several times how other users find out if their hosting has "decent" websites or not, but doesn't know how to do that. Is the assumption that IP/neighbor reputation affects SEO rankings these days and, if so, what's the easiest method to check out who or what might be harming your reputation?

Opting out of Amazon's bandwidth-sharing Sidewalk network

Amazon switched on Sidewalk last week, which is described as a "low-bandwidth network that aims to keep compatible devices connected even when they lose their link to your router." Many Echo and Ring products are automatically being used as bridges to extend the range of the network. See the thread for more info including a link to details of which devices are affected and how to opt-out.
