Скачать или смотреть Gmail Error 550-5.7.25: Why Gmail Is Rejecting Your Emails (PTR / Reverse DNS)

Gmail is increasingly rejecting emails with the 550-5.7.25 error, even from infrastructures that previously worked without issues.

In this video, I explain:

what the 550-5.7.25 Gmail error really means
why Google now strictly enforces valid PTR (Reverse DNS) records
the link between missing PTR, IP reputation, and spam detection
how to check and fix your DNS configuration (PTR, A, HELO)
why PTR records have moved from a “best practice” to a hard requirement

For Gmail, sending emails from an IP without a proper PTR record is now considered a strong risk signal, just like missing SPF or DKIM.

system administrators
IT managers
hosting providers
technical email marketers
companies sending transactional or bulk emails
