Oui, j'ai besoin d'une solution
When I client who uses Mimecast emails us, and mimecast uses opportunistic TLS, SMG rejects the messages with a retry later.
The message header contains a failed TLS negotiation
Unable to initiate TLS - Possible CA Problem - sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
INFO |0716-101804 070|...|||Error Code|21040|Socket closed
The SMG is running the latest updates 10.5.2
We can email the client fine. Anyeon else expercing issues wiht this or similar ?
Why is SMG not falling bakc to clear if TLS negotiation fails. Why is TLS failing ?
thank you in advance
