I want to communicate with our business partners using TLS. Does 4SecureMail support “opportunistic TLS” similar to Exchange when communicating with outside mail servers?
We fully support the same Opportunistic TLS that Microsoft Exchange uses. As long as the outside provider reports that they support TLS in the SMTP handshake, our server will attempt to use it, and this can be verified by looking at the “received” headers in your email. If your partner does not properly advertise TLS or it needs to be otherwise “forced”, we can configure it to always enforce TLS when connecting to a specific server. Keep in mind though, to be fully HIPAA compliant, not only do all hops between servers need to be encrypted, but you must also trust the provider of the servers doing the delivering and that they are secure.
