Hello Quan, Following the rule of thunb "it's a standard with a RFC" I think it makes sense to lend this in James codebase.
My personal preference would be as a guice extension jars, in `protocols/sasl-kerberos` -- Best regards, Benoit TELLIER General manager of Linagora VIETNAM. Product owner for Twake-Mail product. Chairman of the Apache James project. Mail: [email protected] Tel: (0033) 6 77 26 04 58 (WhatsApp, Signal) On Jul 16, 2026 9:23 AM, from Quan Tran Hong <[email protected]>Hi James community, For a customer use case, we are considering extending Apache James SASL support with the GSSAPI mechanism, enabling Kerberos-based authentication as specified by RFC 4752 <rfc-editor.org/rfc/rfc4752.html>. Related Jira ticket: issues.apache.org/jira/browse/JAMES-4215. The intention would be to integrate it with James’s existing SASL infrastructure and make it available to applicable protocols. Would the community be interested in receiving and maintaining this contribution upstream? If not, we may instead implement and maintain it in TMail Backend. Regards, Quan
