To be frank, we have never SWIP’d considering that Apple owns the covering v4 /8, /15 and v6 /29 for these ranges rather than the usual case for a swip where the covering range is owned by an upstream provider.
If you find anything from these ranges that cause abuse issues, you’re of course welcome to email ab...@icloud.com and we can route it to the correct Apple team internally. thanks —srs ________________________________ From: mailop <mailop-boun...@mailop.org> on behalf of Michael Peddemors via mailop <mailop@mailop.org> Sent: Tuesday, April 8, 2025 11:22:38 PM To: mailop@mailop.org <mailop@mailop.org> Subject: Re: [mailop] Outbound IP ranges for iCloud On 2025-04-08 10:20, Suresh Ramasubramanian via mailop wrote: > Hi folks, we are deploying a new set of outbounds for iCloud alongside our > existing ranges.Please update any filtering that you might have.Additionally, > please note that mail from iCloud might ALSO originate from hosts with a > *.apple.com PTR rather than a *.me.com or *.icloud.com PTR.
