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

🔒 Neues Wissen, mehr Sicherheit! 🎓 Ich habe die Masterclass „DomainSecurity“ der InterNexum GmbH erfolgreich absolviert! 🎉 📌 Was wurde gelernt? ✔ Grundlagen Domainmanagement & DNS ✔ E-Mail-Authentisierung (SPF, DKIM, DMARC) ✔ E-Mail-Transport-Sicherheit (MTA-STS, TLS-RPT, DANE) ✔ DNS-Sicherheit (DNSSEC, CAA, TLSA) ✔ BIMI für vertrauenswürdige E-Mails 💡 Und das Beste? Dieses Wissen wird bei Zempel IT Security bereits eingesetzt, um den eigenen E-Mail-Verkehr bestmöglich abzusichern – für mehr Schutz vor Phishing, Spoofing & Co.! 🚀 Sicherheit ist kein Zufall, sondern das Ergebnis von Wissen und Umsetzung. https://zempel-itsecurity.de/home/zis-blog/33-neues-wissen,-mehr-sicherheit-bj%C3%B6rn-zempel-erfolgreich-in-domainsecurity-zertifiziert #DomainSecurity #EmailSecurity #ZempelITSecurity #Cybersecurity #DNS #DMARC #ITSecurity #KnowledgeIsPower

People with businesses & others. FIX YOUR EMAILS! DKIM, DMARC, and SPF aren't options... You end up in JUNK, or, in a lot of cases, NEVER SEEN / BLOCKED. Wonder why you never get any replies... Seriously. Fix your domain records. FUCK! #Tech #Internet #Email #Security #Junk #Junkmail #EmailSecurity

RE: https://infosec.exchange/@zeek/116874651875783351 If you're still manually piecing together separate MIME attachments or body segments during email analysis, you're doing unnecessary work. Zeek has a built-in event that automatically combines it all into a single, cohesive string: https://community.zeek.org/t/zeek-newsletter-issue-64-june-2026/8006#p-29791-zeek-techniques-5 #Zeek #NetworkSecurity #EmailSecurity
