piperino why you want to do that? settings are for receiving domain. isn’t “classydev.fr” the hosted domain on your mailcow instance? just remove it, let TLS settings alone. except you have some legal obligations with some domains to do mandatory TLS. “smtp_tls_security_level = dane” is already set as default and that’s perfectly fine. read - > https://www.postfix.org/postconf.5.html#smtp_tls_policy_maps if thats not the issue, provide the logs from the whole sequence from the connect till the quit.
classycraft3r I wanted to make the TLS work as for now GMail marks my emails as insecure because it is missing it.
gamearoo its not set as “smtp_tls_security_level = dane” it was set to “smtp_tls_security_level = may” and if i switch it to dane mail will fail to send entirely
piperino gamearoo run docker-compose exec postfix-mailcow postconf -n |grep “smtp_tls_security_level =” and check the output. dane is default. if you not messed around.
piperino gamearoo try docker compose exec postfix-mailcow postconf -n |grep “smtp_tls_security_level ="
gamearoo if i type the comman manual this happens if i type the comman manual this happens ok nvm got a response back tho i do get this issue
gamearoo that started after changing it from may to dane its defaulting to may when i install mailcow
gamearoo piperino both my datacenter did tell me this tho Unfortunately, encrypted email services typically do not work in our network due to the smtp proxies. no clue if that plays a role
piperino gamearoo ok if your smtp proxy is not offering TLS towards gmail than your issue. [unknown] are you proxying outgoing smtp traffic too ? [unknown] are you proxying outgoing smtp traffic too ?
