Don't know about SpamCop's listing criteria but I expect the PDML is probably on some blocklists. This is because the PDML is an "unconfirmed" mailing list: When you sign up, you start receiving list mail immediately, without any confirmation step. This sounds innocuous in and of itself, but due to the nature of SMTP it's easy to fake a "from" address and sign up someone else without their knowledge or permission. And it probably, sadly, won't surprise anyone to learn that there some dirtbags out there who've written software that lets you sign your chosen victim up for thousands of mailing lists with a single click :( Imagine getting signed up for a thousand (or more) mailing lists with as much traffic as the PDML and having to unsubscribe from each one. This kind of thing has even been used to bring down mail servers of some smaller providers. IIRC, the PDML used to have subscribe confirmation. Don't know if the listmeister has changed list software or just changed settings but if anyone is having list traffic blocked it might be a good idea for you to ask your provider to whitelist it. After all, you're sending that monthly cheque to them, Doug isn't ;-)
