How can they know if you have or haven't ever sent spam? It's a dynamic
address, so there's no point in trying to track address-specific history.
They simply assume that mail sent directly from dynamic addresses is vastly
more likely to be spam than legit, since it's so rare for people to run
real mail servers through such services.

No it won't. If you relay through your ISP, the source address of the TCP
connection will be the ISP's mail server.
Many ISPs implement rate limits on their mail servers, so spammers will not
find it effective to send out through them. This is one reason why they
either try to send directly from their own machines (which the anti-dynamic
filter blocks) or look for open relays (but these are soon blacklisted).
