E-Mail selbst hosten (eh23)

E-Mail selbst hosten (eh23)

Author: CCC media team April 4, 2026 Duration: 51:31
E-Mail gilt als kompliziert und kaum selbst betreibbar. Trotzdem ist es das größte wirklich dezentrale Kommunikationsmittel. Dieser Talk ist ein Realitätscheck für technisch versierte Menschen mit Hosting-Erfahrung, die sich bisher nicht an einen eigenen Mailserver herangetraut haben. Wir schauen uns an, wie E-Mail heute tatsächlich funktioniert, warum Reputation wichtiger ist als Software und weshalb das größte Problem beim Mailhosting kein technisches, sondern ein soziales ist. Der Talk richtet sich an interessierte Hacker, die ihre Mails selbst hosten wollen und sich ggf. bis jetzt getraut haben, vielleicht auch weil sich Reddit einig ist, dass man Mail unter keinen Umständen selbst betreiben will. Konkret werden folgende Themen angesprochen: * Die Meinung im Internet * High-Level Einblick in Mail-Delivery * Trust-Issues zwischen Providern/Mailservern * Wichtige Punkte beim Setup: * Hoster & IP Reputation * DNS (MX & PTR, rDNS, SPF, DKIM, DMARC) * Fallstricke Mailserver-Konfiguration (Open Relay, HELO) * Deployment-Arten ("Custom", Mailserver Suites: Mailcow, docker-mailserver) * Komponenten: Postfix/OpenSMTPd, Dovecot, rspamd, Sieve, Certbot * RFC2142 Mailboxen * Mailserver Testing Services (MXToolbox, DNS Record Validation, Mail delivery tester) * Große andere Mail Provider * Delivery Testing * Delisting-Prozesse mit Beispiel * Delivery-Probleme debuggen * Altlast-Migration mit imapsync This work is licensed under CC BY-NC 4.0.
