Steve_FR Hello all I see some TLS SNI not matched in my postfix log I use traefik community supported config from : https://docs.mailcow.email/post_installation/reverse-proxy/r_p-traefik3/?h=traefik this config use certdumper my sni.map is empty I have no apparent problems; I send and receive my emails.
