Request for Routing Mail from Kumo MTA Server to PMTA Server by IP

get-help
1

I am seeking assistance in routing an email from the Kumo MTA server to another PMTA server. Is there an available option for this task? Essentially, I am looking to route the message based on IP addresses, such as from 1p-1 (Kumo MTA server) to ip-2 (PMTA server).

Hey there @kindhearted-deer, while we would like to respond to every question raised here, the frequency and nature of your questions are far beyond what we at Kumo Corp can support without financial support from your organization.

You may continue to ask questions in the hope that someone from the broader community will help, but you should expect that Kumo Corp will not spend any time beyond a cursory glance to see if your questions are well-qualified and can be easily dealt with.

This is documented. search for smarthost

Wait… let me Google that for you…

standard network rules apply so if you don’t want to use a hostname, you can use a bracketed IP address.

Your project would benefit from a paid PS consultation where we can answer these and other questions that will specifically get you to a successful conclusion much faster.

Error shown while enabling routing

KumoMTA internal: failed to connect to any candidate hosts: TLS is not enabled and AUTH PLAIN is required. Skipping (ResolvedAddress

Hey there @kindhearted-deer, I see you had AUTH PLAIN in your snippet. The AUTH PLAIN part of an SMTP trace reveals the auth credentials; they are only obscured by base64 encoding, not encrypted.

If you didn’t redact your credentials, I recommend deleting the snippet and changing your credentials.

@faithful-ostrich @yearning-hyena Please help me to configure routing

trying with
enable_tls = ‘Disabled’
This is also not working

12

maybe also try enable_mta_sts = ‘none’
according to the docs it should force enabler_tls to be honored…
I think in my shaping.toml I used: enable_mta_sts = false
which might do the same as none

kumomta requires TLS in order to use auth. If you cannot provision TLS, you must disable auth
