I start to investigate the spam issue I have with #Yunohost
1) Rspamd is running correctly
2) None of the spam have Headers with a score
3) The spam has been analysed by rspamd
4) My spams have all a corrupt DKIM header ( not even an invalid sign )
I my first thought, i need to push higher the DKIM score check.
The current score is 3.45 for this spam. I think the threshold is 4 for graylist and 8 for add header.
I don't even know what I'm doing
Further investigation demonstrate that my spams are signed correctly with DKIM. So I will attack another angle : NIKER LES SPAMMEURS ALA RACINE🔥 🔥 🔥 🔥 🔥 🔥
#SpamStory continue I found 2 IPs ranges and contact abuse email but I havn't a lot of faith about that, then I will investigate in the content of each email and extract base64 encodind then investigate the HTML body, extract links, domains, whois and stuff
I'm a french guy alone here.
