And updated the security level to "secure".

If I turn this to "secure", I get in maillog file:

server certificate verification failed for
smtp.gmx.com[212.227.17.174]:465: num=62:hostname mismatch

The cert is signed for mail.gmx.com, either change the relayhost setting
to reflect this or create a new cert that also includes smtp.gmx.com.

Changing the relayhost does not change the behavior: turning security

looks you have misconfigured smtp_tls_verify_cert_match:


smtp_tls_verify_cert_match = pingala.fqdn

http://www.postfix.org/postconf.5.html#smtp_tls_verify_cert_match

perhaps unset it and try if the default work.
