Hi, We’ve setup postfix on our RHEL7 SMTP servers with TLS fingerprint authentication for the SMTP submission process. It works great for our other Linux and OSX hosts.
We’ve had requests for help making it work with Windows, specifically from Powershell. We tried connecting using the Powershell methods described by Microsoft for SMTP TLS auth, but while debugging from the Postfix side the client doesn’t appear to ever send the certificate. Is there anyone else on this list who uses TLS fingerprints and has it working with Windows client - via Powershell or any other Windows method ? Thanks, Craig
