How to hide KumoMTA from the header?

In the emails, there’s a header that looks like this:

by megazord (KumoMTA)
with HTTP id 12345 for simoncpu@awesome.example.com;
Fri, 7 Mar 2025 21:04:27 +0000```

Is there a way to hide "KumoMTA" from the header? Thanks!

You’re ashamed of us?! :wink:

check out trace_headers - KumoMTA Docs

@yearning-hyena hehe… we’re just hiding as much info from competitors :slightly_smiling_face:

@free-spirited-yorksh awesome, thank you!

ahhh… does this setting this work on start_http_listener as well? we’re currently sending the emails via HTTP

Only for paid customers. ;p

No, one sec while I check.
