Technical Guide & Sysadmin Recommendations
Authored by HostRating.org Engineering TeamAchieving 10/10 Deliverability with Dedicated Mail IP Subnets
In 2024 and 2026, Google and Yahoo enacted strict requirements: bulk senders must have valid SPF, DKIM, DMARC, and matching Forward-Confirmed Reverse DNS (FCrDNS). One bad neighbor on a shared host can blacklist an entire subnet.
Dedicated KVM VPS instances from Virterion and IwiHost provide pristine dedicated IPv4 addresses with configurable PTR records, ensuring your business correspondence never gets flagged as junk.
