SSL Certificates in SpamTitan Gateway

SpamTitan Gateway can use SSL certificates for:

  • HTTPS: to ensure that all HTTP traffic to and from the SpamTitan Gateway UI is encrypted.

    • Go to HTTPS > Access/Authentication > Settings to select a certificate for HTTPS.

  • TLS: to encrypt inbound email traffic.

    • Go to Settings > TLS to select a certificate for TLS.

SpamTitan uses .pem format certificates. Certificates can be converted from one format to another using the open-source utility OpenSSL to perform the conversion, or an online conversion service, such as SSL Converterexternal_link.png (TitanHQ are not endorsing this site, it is just being used as an example).

SSL certificates are linked to a specific hostname or domain, for example, or * To avoid issues, ensure your certificate matches your server name or domain.

There are two types of certificates you can use:

  1. Trusted certificates: These are signed by a trusted certificate signing authority. This type of certificate can be used for encryption and also tells your customers that the server information has been verified by a trusted source.

  2. Private (self-signed) certificates: A self-signed certificate can be used for encryption, but can not be used to verify server information.
