Re: [mailop] Moving email server to new IP
IP rep is a big deal, still. You might want to keep the existing IP. Or if you do plan to keep it, relay mail from your new server through it. SMB/low volume mail is the trickiest to sort of IP warm correctly, so I honestly expect you'll have some pain. Here and elsewhere you'll find people complaining that Gmail is completely unfair to the small volume sender. Sounds like you're smarter than most, but it's still tricky, both with Gmail and Microsoft. I'm having similar concerns myself, as I move a lot of what I do into AWS, I don't want to lose the sending reputation of my legacy hosted server that I've had for years, so I'm going to keep it, basically just as a mail relay.

Re: [mailop] Moving email server to new IP
How exactly does one ramp up the volume when migrating to a new mail server? I once asked an ISP and never got a real answer. I couldn't see how to send 10% to the new server today, 20% tomorrow, etc. On Thu, Jul 7, 2022, 11:14 AM DJ Anderson via mailop wrote: > Before putting it into service I would check it against the known > blacklists. > > If its clear there and you have your rDNS,SPF,DMARC,DKIM records setup > correctly you should be safe.

I went through something similar about a year ago and blogged about my experiences and shared my "cheatsheet". Not sure if a link to own publications (CC-BY-SA) are fine on this list - I'm mostly a passive reader here. ;-) But I'll follow-up directly with you. In general, checking several blocklists and some manual checks did the trick for me. Note, however, that my experience is based indeed on low mail volume.

Re: [mailop] Moving email server to new IP
Before putting it into service I would check it against the known blacklists. If its clear there and you have your rDNS,SPF,DMARC,DKIM records setup correctly you should be safe. That being said I usually monitor the logs of the newly online server\address to ensure it isn't getting blocked. My other recommendation would be to slowly ramp up message volume rather than just going from 0 to 10k messages a day if you can. That should help with the reputation as well.

IP Reputation is still going strong! Only so many IPs out there, but virtually unlimited domains and content patterns.. As long as your own ARIN block wasn't previously owned by a bad guy, you should have no problems, as long as everything is correctly configured. Common gotcha? Having IPv6 enabled, and not addressing configuration for that. To keep it simpler, start with just IPv4, and then look at IPv6 later when you are ready.. For the record for others, you might like to include the ARIN numbering you intend to use, when asking questions like this. And of course, use a reputable upstream in your routing. Oh, and you might like to get an IP reputation alerting tool active when you first start, eg like HetrixTools or MXToolBox -- "Catch the Magic of Linux..."
