Topic: How do I troubleshoot spam getting through with high score?

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version: 1.6.8
- Deployed with the downloadable installer.
- Ubuntu 20.04.6 LTS
- MySQL
- Web server: Nginx
- iRedAdmin-Pro

I have the spam score set at 2, but mail with a spam score of 10 is getting through.
I have tried inspecting config files and looking at logs, but I am missing something.
I suspect  that I may have whitelisted something I shouldn't have. Where do I look?

I know it says whitelisted, but Where? Every spam email is from different IPs, different addresses. All the emails say whitelisted. Where do I look? They are not on any whitelist.

Re: How do I troubleshoot spam getting through with high score?

I think I found it. The domain of the mail server itself was on a whitelist. This was whitelisting all email. The sender is listed in this format "srs0=gj/d=jn=bounces.indeed.com=msprvs1=19764h-gkmi3l=bounces-294276@mail.server.com", so whitelisting "mail.server.com" would whitelist all incoming email.
