[Rspamd-Users] Can not get ARC signing working

[Christian Rößner]

Hi,

I try hard to get ARC signing working in current master branch. I have one key for all domains. I tested with an address from @roessner.email and sent to a icloud.com address. Also tested the other direction as well. No luck.


/etc/rspamd/local.d:
-----------------------------------------------------------
allow_hdrfrom_mismatch = true;
allow_username_mismatch = true;
check_pubkey = true;

path = "${DBDIR}/arc/default/BD87C431-DD13-4C61-99A3-446B863A64D6.key";
selector = "BD87C431-DD13-4C61-99A3-446B863A64D6";
-----------------------------------------------------------


ls -l /var/lib/rspamd/arc/default:
-----------------------------------------------------------
-rw-r----- 1 root rspamd 1704 Jun 14 10:26 BD87C431-DD13-4C61-99A3-446B863A64D6.key
-rw-r--r-- 1 root root    413 Jun 14 10:27 BD87C431-DD13-4C61-99A3-446B863A64D6.pub
-----------------------------------------------------------


host -t txt BD87C431-DD13-4C61-99A3-446B863A64D6._domainkey.roessner.email:
-----------------------------------------------------------

I do not see ARC_SIGN in the list of symbols and the header is not created. I also have turned on debug for arc, but it does not create lines in sending (outbound) direction. In inbound direction it tells me that it ignores signing, because the user would be unauthenticated. Even if I set "auth_only" to false does not change this.

I am stuck. Does someone know how to set this up correctly?

Kind regards

Christian
