Sendmail sits in the path of every email transaction your organization sends or receives. It logs auth attempts, TLS negotiations, relay IPs, forged hostnames, and rejections. Most teams treat that as noise. It's early-warning threat telemetry. The Sendmail Content Pack for Graylog parses those logs into GIM-mapped events and a six-tab Illuminate dashboard, automatically. https://graylog.org/post/sendmail-data-in-graylog/ #SIEM #ThreatHunting #EmailSecurity

Graylog Sendmail Content Pack parses, enriches, and maps mail server logs to GIM, turning routine MTA data into real threat detection signal."
