Common Mail Service IP Addresses

72 次浏览 Markdown

Overview

Some mail services (for example, Google Apps™) allow customers who own their own domains to relay email through different mail servers. If properly-configured SPF records do not exist for the mail service for these customers’ domains, Greylisting may identify them as spam. To prevent this, add these IP addresses and ranges to the Trusted Hosts list in WHM’s Greylisting interface (WHM >> Home >> Email >> Greylisting).
