Having trouble with ipv6 declarations

on sources.toml i only have 2 ipv6 addresses. however it is generating this error: “caused by: deserialize error:
invalid socket address syntax, while processing {“socks5_proxy_server”:“proxyserver3:1080”,“name”:“proxy3”,“ehlo_domain”:“proxy3.juices.digital”,“source_address”:“2606:6680:15:1::456a:2092”,“socks5_proxy_source_address”:“2606:6680:15:1::456a:2092”}”

how i have it on the sources.toml file:
[source.“proxy3”]
source_address = “2606:6680:15:1::456a:2092”
ehlo_domain = “proxy3.juices.digital”
socks5_proxy_server = “proxyserver3:1080”
socks5_proxy_source_address = “2606:6680:15:1::456a:2092”

Hey there @artistic-yorkshire, thanks for posting. Please read the “Troubleshooting” and “How to Ask for Help” buttons below. If you would like a 1:1 support session from the KumoMTA team, details are at the “Book a Support Session” button below.

Remove source_address

It specifies what address to use on the MTA node to connect to the proxy server. You can’t use it on the MTA and on the proxy server.

Most users don’t need to specify source_address when using a proxy unless they have to use a specific one to be on the same network as the proxy when they use multiple interfaces on the MTA.

thanks i’m trying it
