[Rspamd-Users] Can't get DKIM signing to work

[Tino Hendricks]

Dear list!

Module is enabled:

rspamadm configdump -m
Modules enabled: rbl, ... dkim_signing, asn, ...

but this only reports

rspamadm configdump dkim_signing 
*** Section dkim_signing ***
sign_networks [
    "127.2.4.7",
]
Where does this IP address come from?

My /etc/rspamd/local.d/dkim_signing.conf:

sign_authenticated = true;
use_esld = true;
allow_username_mismatch = true;
use_domain = „header";
allow_hdrfrom_mismatch = false;
allow_hdrfrom_mismatch_sign_networks = true;
selector="dkim";

# If false, messages with empty envelope from are not signed
allow_envfrom_empty = true;

# If true, multiple from headers are allowed (but only first is used)
allow_hdrfrom_multiple = false;

# Default path to key, can include '$domain' and '$selector' variables
path = "/var/lib/rspamd/dkim/$domain.$selector.key";

# Symbol to add when message is signed
symbol = "DKIM_SIGNED";

# If `true` get pubkey from DNS record and check if it matches private key
check_pubkey = false;
# Set to `false` if you want to skip signing if public and private keys mismatch
allow_pubkey_mismatch = true;

Why is it looking for the domain in username, despite: allow_username_mismatch = true;

What am I missing?

Thank you so much!
