HIN Gateway
The HIN Mail Gateway based on SEPPmail: clusters, backup, Stargate.
HIN Mail Login: Webmail, Outlook Token, Forgotten Password, and HIN Mail Global
Where and how to sign in to HIN Mail: webmail at webmail.hin.ch, mail tokens for Outlook and smartphones, login without the HIN Client using an SMS code or Authenticator app, password reset, and opening HIN Mail Global as a recipient without a HIN account.
Mail loop with encryption gateway behind EXO - Prevent spoofing issues
If the encryption gateway (HIN in this example) is behind Exchange Online, every incoming message reaches EOP a second time: with a foreign sender domain, an invalid DKIM signature, and the gateway IP as the source. The result is a spoof verdict and junk. Four settings prevent this without disabling filtering using SCL -1: a PTR record, Enhanced Filtering disabled, a spoof exception for the gateway infrastructure, and CloudServicesMailEnabled on both connectors.
HIN Platform Renewal 2026: Access Gateway, Client, and Deadlines Through September 14
Firewall approval by August 14, Access Gateway version 4 from August 17, SAML endpoints, hardware tokens, and HIN Client by September 14. The mail gateway is not affected and will be replaced separately.
Backing up and restoring the HIN Mail Gateway after a failure
A cluster protects the HIN Mail Gateway against node failures, but it does not replace a backup. Configuration, key material, restore sequence and the changes introduced by Stargate are crucial.
HIN Mailgateway 15.0.5: Fixing Login Failures After a Cluster Update
After updating an HIN Mailgateway cluster to version 15.0.5, login fails on both nodes after a few minutes. This procedure restores the appliances to operation in a controlled manner.
