One Domain not Receiving Email - SPAMD issue?

Hey all,

I have one domain on my server that isn't receiving emails. This started in the last week or two. It seems to be an issue with spamd as if I turn it off the emails flow through fine. How can I get the emails being delivered again with the filter on?

Also, which log could I look in to find IPs of spam servers that are sending so I could block them?

I am using cPanel 11.24.4-R35075 - WHM 11.24.2 - X 3.9 on CentOS 4.7.

Ok I have more info now.

Spamassassin for this domain rates almost all emails higher than they are rated coming into any of my other domains (yes this one is a very busy domain). I had to bump the required score up to 8 instead of the default of 5.

So now a lot of messages are being detected as not spam but they are still being bypassed. Here is a log:

2009-04-09 15:58:20 1Ls0O8-0002Lo-08 H=cdptpa-omtalb.mail.rr.com [75.180.132.120] Warning: "SpamAssassin as yadayada detected message as NOT spam (7.6)"

So anyone know why it might be being bypassed? It is only happening on this one domain.
