My ISP doesn't filter anything, I don't think.
I'm using POP and do my own filtering. I don't have anything other than Thunderbird doing mail filtering.
One of the MensHealth.com spams:

I'm rusty at interpreting this stuff, but it looks like it's coming from Poland and being routed through SpamArrest. Is my ISP using SpamArrest and is that the weak link?
Thanks a bunch.
Cheers,
Scott.
