Sadly, it's a pretty common issue to have email sent directly from an IP address range designated as "dynamic" get blocked by various spam filters.
But that's the thing: it isn't a dynamic address. It's part of a block of
addresses managed by Digital Ocean, but it can't change. That's the whole point of providing reverse DNS.

Ed,
When PowerChurch first moved the email servers to RackSpace we had a similar problem. The user that had the IP prior to us may have put an open relay email server on it. This caused a lot of grieve for us. We ended up getting RackSpace to move us to a different IP after a few days of attempting to get off the blacklist servers.
