I recently migrated my long-running self-hosted email server to Hetzner and successfully had ports 25 and 465 unblocked. Despite having low traffic (approximately 100 emails daily) and no history of spamming or improper activities, I’m worried about the possibility of Hetzner IPs being blacklisted, even though neither my server IPv4 nor IPv6 are currently on any blacklists. Has anyone experienced Hetzner IPs getting blacklisted without cause in this scenario?
