Hi again, in egress_source for SOCKS5 Proxy , does it support auth with user:pwd, thanks

It does in the latest dev build, see https://docs.kumomta.com/reference/kumo/start_proxy_listener/

Hi again, can i use it in source_ip.toml directtly, for example: [source.“cheerfulsoul24com-ip”]
–source_address = “15.204.152.144”
socks5_proxy_server = ‘10.0.5.10:5000’,

– Used by the SOCKS5 proxy server to connect to the destination address
socks5_proxy_source_address = ‘10.0.0.1’,
ehlo_domain = “ip144.ip-15-204-152.us”

Yes. And sometimes you would specify both source_address and socks5_proxy_source_address where source_address is saying which IP on the KumoMTA node to use to connect to the proxy server (in case it’s on a different subnet for example) while the socks5_proxy_source_address says which IP on the proxy to use to connect externally.
