This is what happens when I try to send an email using the builtin Windows 11 email client. Despite what the log says Milter service is in fact running at 32b8266a-mailfilter (and works, it is scanning incoming email), so is MariaDB at core-mariadb (I can log in into postfixadmin without issues). I am in fact receiving email using this client without issues (DNS, SSL certificates are all set up correctly).

It is installed and running, I'm using it for nginx proxy manager and nextcloud, postfix admin webui also works fine with it.

I can send email using the postfix webui interface, but not using an external client for some reason.

I've installed Thunderbird and now everything seems to be working fine. The only issue is that the cert files from /ssl directory are not used. letsencrypt_certs: true is set, the correct certs are placed in /ssl (fullchain.pem and privkey.pem) and yet the cert is from Nginx Proxy Manager:

Actual cert:

I have re-checked my setup, turns out it was a configuration issue on my end when it comes to certificates.
