E-mail security at Skymail
Skymail protects your mailbox with modern transport encryption, DNS protection, signed messages and clear safeguards against spoofing, phishing and account abuse.
Security that starts before the message
Many attacks happen before a message ever reaches the mailbox. Skymail combines DNS, transport, sender and account protection into a robust security foundation.
DNSSEC protects skymail.de against manipulation, cache poisoning and forged delivery routes.
DANE, TLSA, MTA-STS and Perfect Forward Secrecy harden the connection between mail servers.
SPF, DKIM and DMARC reduce spoofing and make forged senders much harder to abuse.
TLS-RPT and continuous checks help detect certificate and delivery problems early.
