Hello,we need to authenticate a SMTP client connection base on the CN of the (trusted) client certificate. The client is not under our control (O365 connector), so we will get no notification if the key fingerprint will change. As far as i can see Postfix is only able to use certificate fingerprints to allow relaying, not the CN string, no?
Have i missed something or is this not considered a valid use case? Regards Andreas
