[Rspamd-Users] scams group

[Vu Ngoc VU]

Hello,
Running version 3.2 on Debian ;
While checking rejected messages from web-ui, I've found interesting symbol INTRODUCTION (Sender introduces themselves).
So I've searched for it in the Symbols tab and found it is in « scams » group.

In my /etc/rspamd, the only occurrence to scams is in composites.conf but that is for LEAKED_PASSWORD_SCAM symbol.

Could someone explain to me where I can find the rule for INTRODUCTION symbol in my system please?

Best regards,
