Rspamd segfault and no dkim signature on output mail

Hi, I have a DKIM problem when sending email, don’t know really since when as I have been lazy about it for a long time.

My YunoHost server

Hardware: Odroid hc4
YunoHost version: 11.2.11.3 (stable)
I have access to my server : Through SSH | through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

Trying to send an email, it appears that the mail is not signed with DKIM as I can see on mail-tester report, and on some services sending me dmarc reports.

I’ve been investigating a little bit, and I faced different problems. First one it seems that one day, don’t really know when and how the default dkim domain key disappeared from /etc/dkim folder.
I found it with the following log line :

2024-04-30 20:00:54 #2906834(normal) <439d7c>; task; dkim_module_load_key_format: cannot load dkim key /etc/dkim/quiwy.ninja.mail.key: cannot stat key file: '/etc/dkim/quiwy.ninja.mail.key' No such file or directory

After creating the key, following these script lines ; I had permissions problems, with the following log :

2024-04-30 20:38:05 #2925441(normal) <3e62b5>; task; dkim_module_load_key_format: cannot load dkim key /etc/dkim/quiwy.ninja.mail.key: cannot map key file: '/etc/dkim/quiwy.ninja.mail.key' Permission denied

I fixed it reading the same script as above, just a few lines later.

Now, I guess it should be working, but I have a rspamd segfault when sending an email.
Doesn’t know really what happens, and what I can do to fix it.

The logs are the following :

Do you have any clue on what I could try to fix it? I had a 10/10 mail-tester score when first installing the server, but it was 4 or 5 years ago.

Any help would be appreciated :smile:

Hi,

Anyone has any idea about it ?

Thanks :slight_smile:

Well, after searching a little bit more, and with no more idea, I just tried to update rspamd with the stable repository they provide here : Downloads .

And everything is working fine now. I know it’s not a perfect solution, but at least it works, no more segfault and DKIM signature working fine :smile: .
