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. For checking black lists I like to use https://mxtoolbox.com/blacklists.aspx DJ Anderson Techwebhosting ----- Original Message ----- From: "Nate Burke via mailop" <mailop@mailop.org> To: mailop@mailop.org Sent: Thursday, July 7, 2022 1:41:32 PM Subject: [mailop] Moving email server to new IP I've had a small multi-domain business mail server running on the same IP for the last 20 years, I need to change the IP from an address in a reassigned IP block, to my own ARIN block. Is IP reputation still a big deal, or are anti-spam measures now content/quantity based and the IP address isn't as important anymore. Can I just flip the IP and update my DNS/SPFs and be good.
