Facing TLS issue

get-help

“response”:{“code”:400,“enhanced_code”:null,“content”:“KumoMTA internal: failed to connect to any candidate hosts: TLS handshake with ResolvedAddress { name: "_dc-mx.3e1c0907443f.vinmail.io.", addr: }:25 failed: invalid peer certificate: NotValidForName”,“command”:null}

iam using below configuration to disable TLS

kumo.start_http_listener {
listen = ‘127.0.0.1:8000’,
tls_certificate = ‘/etc/letsencrypt/live/kumomta.salesjio.com/cert.pem’,
tls_private_key = ‘/etc/letsencrypt/live/kumomta.salesjio.com/privkey.pem’,
use_tls = false
}

But above is not working. Is there any other option ?

use_tls = true hope this will work

start_http_listener is for KumoMTA to respond to http requests, was that your intent when configuring tls? Your error message would imply otherwise.

The error message is for outbound delivery the configuration you showed was for inbound reception. To disable outbound TLS set enable_tls = Disabled in the outbound shaping config.
